The synthesis isotactic polymers is usually only possible by means of special stereospecific (stereoregulating)initiators . 通常只能用特殊的立体定向（立体调节）引发剂来合成等规聚合物。
Impurities that promote deterioration of polymers can be foreign materials, such as residues from polymerization catalysts . 促使聚合物劣化的杂质可能是外加的物质，如残存的聚合用催化剂。
The liquid polymer is stored in a container in the fire truck and pumped into the water that will travel through the hose . 此液体聚合物储存在消防卡车里的容器内，通过皮管将它压注于水中。
The drying of wet polymer particles with solvent recovery is an operation which may see wide use in the plastics industry . 干燥湿的聚合物颗粒并把溶剂回收是在塑料工业中有广泛用途的一种操作。
Polybutadienes, epoxy resins, and similar polymers may be used while they are in the viscous or liquid state of prepolymerization . 聚丁二烯，环氧树脂及类似聚合物在粘性状或液体预聚态都是可用的。
Difunctionality, which is the essential characteristic of a polymer precursor, may be achieved in many different ways . 能生成聚合物的物质其不可缺少的特点是具有双官能性。这种双官能性可用多种方法获得。
