The changes in molecular weights, their distributions, and initial rates have been measured, for a series of polystyrenes prepared by thermal and anionic procedures. The information obtained and previous results can be explained to a very large extent by a kinetic chain decomposition comprised of competing end and random initiation, depropagation, intra- and intermolecular transfer and termination by combination.
对于一系列通过热聚合和阴离子聚合方法制备的聚苯乙烯，已测定其分子量、分子量分布及初始速率的变化。所获得的信息及先前的结果在很大程度上可用由竞争的端基引发和无规引发、解聚、分子内和分子间转移以及偶合终止所构成的动力学链分解来解释。
