高分子化学常见名词（中英文）

?Biopolymer

A polymer produced by a living plant, animal fungus, bacterium, or

other biological entity.

生物高分子：生物高分子是一种由活的植物、生物真菌、细菌或其

他生物体提炼出的一种聚合物。

?Ceiling Temperature

Above a certain temperature, monomers can no longer be persuaded to

form polymers by chain polymerisation. This occurs when the loss

in entropy arising from joining many molecules into one outweighs the

energetic benefit of converting double bonds to single bonds. A

chain-growth polymer raised above the ceiling temperature will

degrade, or depolymerise.

聚合上限温度：单体聚合时，当聚合和解聚处于平衡状态，这时的

聚合温度称为聚合上限温度。当反应温度高于聚合上限温度时，聚

合物会解聚成小分子单体。

?Plastic

What most people think of when they think of polymers. Strictly

speaking, a plastic is a polymeric material that can be molded into

different shapes when heated (a thermoplastic) - this is true for most

of the materials mentioned on this website, including poly(styrene),

nylon66, PVC, and PET. Some misguided people say nasty things about

plastic, but it wouldn't be everywhere if it wasn't (a) incredibly useful

and (b) incredibly cheap.

塑料：从严格意义上来讲，塑料（热塑性）是一种加热后可以浇铸

成不同形状的聚合物，包括聚苯乙烯、尼龙66、PVC、PET等。

?Elastomer

A polymer that, when deformed (stretched, twisted, spindled, mutilated,

etc.) springs back into its original shape. The elastomer par excellence

is lightly-crosslinked natural rubber.

弹性体：弹性体是一种发生形变（如拉伸、扭转、损坏等）后能够

恢复原始形状的聚合物。性能最优异的弹性体是轻度交联的天然橡

胶。

?Fiber

Fibers are polymers that have very high resistance to deformation-they

undergo only low elongation( <10-50%) and have very high

moduli(>35000N/cm2) and tensile strengths (>35000N/cm2).

（<10-50％），模量很高(>35000N/cm2)，抗张强度很高

(>35000N/cm2)。

of the earliest was ABS (Acrylonitrile-Butadiene-Styrene) rubber,

a copolymer containing long segments of each of those three monomers.

合成橡胶：合成橡胶的性能类似于天然橡胶的性能。最早的合成橡胶品种是ABS（丙烯腈－丁二烯－苯乙烯）橡胶。

?Free Radical

A member of the socialist party not caught by McCarthy's inquisition.

Also a molecule which has an odd number of electrons. The "unpaired"

electron feels lonely and wants to find a friend. If it finds something that might be willing to give it an electron it reacts very quickly with it.

Molecules such as other radicals and alkenes turn out to be good things for radicals to attack. The reaction of radicals with the double bonds in alkenes is how some of us earn our living.

自由基：化合物中共价键发生均裂时，共价键上两个电子分属于两个基团，这种带独电子的基团呈中性。

?Side groups

All the carbon based polymers you will find mentioned on this site have the structure -C-C-C-C-C-C- etc. Anything hanging off that centre chain that is not a hydrogen atom is a side group.

侧基：任何悬挂在高分子主链上的非氢原子均称为侧基。

?Functional Group

An atom or group of atoms that has similar chemical behavior, no matter what the rest of the molecule looks like. For example, the hydroxy (OH) group in all alcohols has similar reactivity, as does the thio (SH) group in all thiols.

官能团：分子中存在的一部分原子、原子团或特征结构，容易发生体现分子主要性质的某些特征反应，因此称它们为官能团。

?Hydrogen bond

The strongest attraction between two dipoles is when one or both of

them involves a bond between hydrogen and a strongly

electronegative atom, like oxygen, fluorine, or nitrogen. Because

hydrogen only has one electron, if it forms a bond with an element that is very keen to grab an electron, it becomes much more positive than an element that has plenty of other electrons left to hang around the

positively charged nucleus. Dipole-dipole interactions between these sort of molecules (like water {H2O}, ammonia {NH3}, hydrofluoric

acid{HF}) are so much stronger than ordinary dipole-dipole bonds that we give them the special name of 'hydrogen bonds'.

氢键：氢键是极性很强的X－H键上的氢原子与另外一个键上电负性很大的原子上的孤对电子相互吸引而形成的一种键。氢键作用力比一般的偶极间相互作用力大。氢键具有饱和性和方向性。

?Oligomer

An oligomer is a molecule which is formed from a few smaller

(identical) molecules joined together. Just as a monomer is one (mono)

unit (mer) and a dimer is two (di) units, an oligomer is a few units.

低聚物：低聚物是几个分子单元连接而成的分子。

?Hydrolysis

Hydrolysis is a reaction where water attacks a part of a molecule,

usually breaking it up. An example of hydrolysis is the breaking of the ester linkages to form a soap out of an oil. In this reaction, the ester linkage is broken, releasing an alcohol and an acid.

水解：水解是水攻击分子时使其发生断裂的反应。如，酯键水解，释放出醇和酸。

?Nylon

A class of polymers that is widely use in the clothing industry (amongst

others). Their common feature is the presence of a -C(O)-NH- link

between monomer units. This is also called a peptide bond. See Nylon 66 and Nylon 6.

?Nylon 6

Another form of nylon that uses only one monomer unit (not two). This monomer is difunctional with a carboxylic acid group at one end and an amine. group at the other. The condensation reaction between two

such molecules produces an amide bond in the same way as the

synthesis of Nylon 66. The monomer used is (I think)

7-amine-1-heptanoic acid.

尼龙6：尼龙6仅由一种单体－己内酰胺聚合而成。也可由7－氨基－1－庚酸自缩聚而成。

?Nylon 66

A polymer widely used in a fibrous form in fabrics as well as solid

lumps of plastic (e.g. in chopping boards and bearings). Nylon 66 may be formed from the condensation polymerisation of

1,6-hexadiamine and 1,8-octadioic acid, although modern industrial

processes have improved upon these reactions by ionising the reagents to the hexadiammonium and 1,8-octadioate ions before the reaction is undertaken.

(-C-O-C(O)-) to join the monomer units. Polyesters are condensation polymers.

聚酯：聚酯是一类通过酯键将单体连接起来的聚合物。聚酯是缩和聚合物。

?Thermoset

A polymer that, when heated ('thermo') does not become soft and

deformable. This is usually because it is crosslinked, and the molecules comprising it cannot move past one another unless chemical bonds are actually broken - which leads to the decomposition of the polymer.

Phenol-formaldehyde resin is an example.

热固性树脂：热固性树脂是加热后不会变软，不会发生形变的一种高聚物。热固性树脂通常具有分子链交联结构。如酚醛树脂、环氧树脂等。

碳阳离子：正电荷位于碳原子上的一种正电性的化学物种，碳正离子（三个键连接在带正电的碳上）和碳鎓离子（有五个甚至更多的键连接在正电性的碳上）都属于碳阳离子。

?Carbonium

If there are five or more bonds to a single carbon atoms, it will be short of electrons and have a positive charge - this species is called a

carbonium ion, a form of carbocation. The easiest way to make one is to add a hydrogen ion (H+).

阳碳（碳鎓）：如果有五个甚至更多的键连接在一个碳原子上，碳原子由于缺乏电子而带正电，这种物质称为阳碳（或碳鎓），这是碳正离子的一种。形成阳碳的最简单的办法就是加上一个氢离子。

many smaller molecules ( monomer) covalently bonded together. Some of us think they are much better than any of those little molecules, but the other chemists are always telling us size doesn't matter.

聚合物:由许多小分子（单体）通过共价键连接而成的大分子物质（分子量大于1万）。

?Polymerisation

The process in which many small molecules (molecular weight ~100) are joined together to form a few, much larger molecules (molecular weight 10 000 - 10 000 000). The two ways in which this happens are chain-growth and step-growth polymerisation.

聚合:许多小分子物质（分子量约为100）连接在一起生成高分子（分子量为104－107）的过程。主要有连锁聚合和逐步聚合两大类。

?Comonomer

to make a copolymer. All the different comonomers used in a

copolymerisation are incorporated into each chain.

copolymer has each of its comonomers. in every chain. There are a

number of different types of copolymer which describe the nature of the arrangement of the comonomers. within the polymer chain. For the two monomer units A and B we can have:

block:...AAAAAABBBBBB...

polymers in which every polymer chain grows continuously through the course of the reaction, remaining quite small until almost all the

monomer has reacted.

缩合聚合又称作逐步聚合，每一个聚合物链都是通过一个反应过程连续增长的，在这个反应过程中，聚合物的分子量是与单体的转化率成正比的。

?Radical Chain Polymrization

Chain polymerization is initiated by a reactive species R* produced from some compound I termed an initiator. The reactive species, which may be a free-radical, adds to a monomer molecule by opening the p-bond to form a new radical. The process is repeated as many more monomer

molecules are successively added to continuously propagate the reactive center. Polymer growth is terminated at some point by destruction of the reactive center by an appropriate reaction depending on the type of

reactive center and the particular reaction conditions.

自由基聚合由一种称为引发剂的化合物产生的反应种所引发的链式聚合。这个带有自由基的反应种通过打开双键加入到单体分子上，从而形成新的自由基。这个过程不断重复，更多的单体连续地加入到反应中心上，形成大的自由基反应中心。当一种破坏反应中心的反应发生时，聚合物增长被终止，这将依赖于反应中心的类型和特定的反应条件。

?Addition Polymerisation

Also known as chain-growth polymerisation. The mechanism in

which large numbers of usually identical small molecules are joined

together to rapidly form a single large molecule. This involves the

addition of reactive centre (anion, cation, or unpaired electron) to a multiple bond to form a new bond and a new reactive centre - which

reacts with another multiple bond, et cetera... The finished chain then hangs around without reacting while more of the starting material reacts to form new polymer chains.

加成聚合又称为连锁聚合。聚合机理是，大量的小分子快速地连接在一起形成一个大分子。反应中心（阴离子、阴离子和不成对电子）加成到单体的双键中生成新的键和新的反应中心，之后再与另一个单体反应，以此持续反应下去。当不再反应时，链的增长停止，同时新的反应开始，生成新的聚合物链。

?Living Polymerization

Living polymerization are polymerizations in which propagation centers

do not undergo either termination of tranfer.

活性聚合活性聚合是指增长中心不会发生链终止和链转移的聚合反应。

?Solution Polymerization

Solution polymerization is carried out by dissolving the monomer in a solvent. The solvent acts as diluent and aids in the transfer of the heat of polymerization. The solvent also allows easier stirring, since the

viscosity of the reaction mixture is decreased. Thermal control is much easier in solution polymerization compared to bulk polymerization.

溶液聚合溶液聚合是将单体溶解在溶剂中来实现的。溶剂起到稀释的作用，有利于聚合反应热的传递，同时由于溶剂使反应混合物的粘度降低，使得搅拌较为容易。与本体聚合相比，在溶液聚合中对反应热的控制比较容易。

?Suspension Polymerization

Suspension polymerization is carried out by suspending the monomer

(discontinuous phase) as droplets (50-500mm in diameter) in water. The water: monomer weight ratio varies from 1:1 to 4:1 in most

polymerizations. The monomer droplets are prevented from coalescing by agitation and the presence of suspension stabilizer.

悬浮聚合悬浮聚合是将直径为50～500毫米的单体液滴（不连续相）悬浮在水中来实现的。在大多数悬浮聚合中，水与单体的重量比为1:1到4:1。可通过搅拌和加入悬浮稳定剂来阻止单体液滴的聚集。?Depolymerisation

The chemical reaction which results in a polymer chain being broken up into monomer units. For most polymers. made by addition

polymerisation, this is done by heating the polymer above its

ceiling temperature in the absence of oxygen. Some polymers, like styrene and vinyl chloride, will be difficult to depolymerise because the bonds between the side-groups (the phenyl ring and chlorine in

these examples) are weaker than the C-C bonds between ex-monomers, and the polymer will degrade into different species than the starting

materials. Other polymers, such as those made by step growth

polymerisation may be more easily depolymerised. by undoing the condensation or elimination reaction that caused the monomer units to

join. In the lab, this can often be done using a strong acid in harsh

conditions, although industrially, there are other tricks that polymer

scientists can play.

解聚一种导致聚合物链断裂生成单体单元的化学反应。对于由加成聚合得到的大部分聚合物而言，在氧存在下加热到它的临界温度以上，聚合物就会解聚。但聚苯乙烯和聚氯乙烯类的聚合物的解聚就比较困难，因为侧基的键（如苯环和氯）比单体的C－C键弱，聚合物在解聚成单体前就降解成各种产物。其它聚合物，如由逐步聚合得到的聚合物，比较容易解聚，可通过引入导致单体单元链接的

缩和反应的逆反应来实现。在实验室中，可以在特殊的条件下用强酸解聚；在工业中，聚合物科学家用其它方法来实现解聚。

?Dimer

A dimer is two molecules (of the same type) bonded together. (just as

monomer is one (mono) unit (mer) a dimer is two units).

二聚体二聚体是同一类型的两个单体分子键和的产物。即，单体是一个单体单元，而二聚体是两个单体单元。

The prepolymer is obtained in a first step by stopping the reactionm

usually by cooling, at the desired extent of conversion.

预聚物通常通过冷却终止反应，获得具有设计转化率的预聚物。

The ratio is also referred to as the polydipersity index.

多分散指数是指（重均/数均）的比值。

?Initiator

A compound required to start a chain reaction, such as free-radical

polymerisation. Unlike a catalyst, it is consumed in the reaction, but only a small quantity is normally required since one molecule of

initiator can initiate the reaction of many other molecules.

引发剂能够引起连锁反应（如自由基聚合）的化合物。与催化剂不同，引发剂在反应中能被消耗掉，但是一般只需要少量的引发剂，因为一个引发剂分子能够引发许多单体分子的反应。

?Kinetic Chain Length

The kinetic chain length n of a radical chain polymerization is defined as the average number of monomer molecules consumed (polymerized) per each radical, which initiates a polymer chain. This quantity will

obviously be given by the ratio of the polymerization rate to the

initiation rate or to the termination rate, since the latter two rates are

equal.

动力学链长自由基聚合物的动力学链长n定义为每个引发聚合的自由基所消耗的单体分子的平均数。它等于聚合速率与引发速率（或终止速率）的比值，因为引发速率与终止速率相等。

Monomer reactivity ratios is the ratio of the rate constant for a reactive propagating species adding its own type of monomer to the rate constant for its addition of the other monomer.

单体竟聚率是指反应增长种加成到同种单体的速率常数与它加成到其它类型单体的速率常数之比。

?Initiator Effciency

引发剂效率引发剂效率定义为，引发剂最初分解形成自由基，并成功引发聚合反应的分数。引发剂效率不包括因诱导分解所浪费的引发剂。

?Chain Transfer

A growing polymer is terminated by the transferred of a hydrogen or

other atom or species to it from some compound present in the

system-the monomer, initiator, or solvent, as the case may be. These

radical displacement reactions are chain-transfer reactions.

链转移氢、其它原子或反应种转移到反应体系的化合物中（单体、引发剂或溶剂），从而导致聚合物增长终止，这种情况称为链转移。

这种自由基转移的反应称为链转移反应。

?Gel Point

At this point, termed the gel point, one first observes the visible

formation of a gel or insoluble polymer fraction. As the polymerization and gelation proceed beyond the gel point, the amount of gel increases at the expense of the sol as more and more polymer chains in the sol are

crosslinked to the gel. There is a dramatic physical change that occurs during the process of gelation.

在凝胶点，可看到凝胶或不可溶的聚合物生成。当聚合超过凝胶点时，凝胶量增加，越来越多的聚合物链交联成凝胶。在凝胶的过程中，聚合物的物理性质发生巨大的变化。
