美国伊斯脱门公司(Eastman Chem.Corp.)近年来用α-烯烃试制新型高分子化合物称之为“聚异分体”(polyallomers)。这一名称是从希腊文poly(聚合的意思)、allos(异源的意思)、meros(部分的意思)等衍化出来的。表示这种高分子化合物的化学组成,不是单一的单体,而可以包括两种或两种以上的单体。这就是与纳塔教授所发现的定向聚合物不同的地方。这种高分子聚合的方法,叫做“异分聚合”(allomerization),这一术语包含的内容是:聚合物的组分可以是变化的,而其结晶形状则是固定的。这又与一 In recent years, Eastman Chem. Corp. has been trying out new polymers with α-olefins called “polyallomers.” The name is derived from the Greek poly (polymerization meaning), allos (heterologous meaning), meros (part of the meaning) derived. Indicates that the chemical composition of such a polymer compound is not a single monomer but may include two or more monomers. This is where Professor Natta’s discovery of a directional polymer differs. This method of polymer polymerization, called “allomerization,” encompasses the fact that the composition of a polymer can be varied while its crystalline shape is fixed. This again with one
