| 摘 要： | 采用一种新的研究方法,进行了苯乙烯阴离子的高温本体聚合,突破了传统阴离子动力学研究中仅采用高真空、稀溶液、低转化率的局限.结果表明:当聚合转化率小于4%时,聚合反应机理完全符合经典阴离子活性聚合的理论;但继续聚合后将出现一个转化率停滞平台和聚合速率再次升高的现象,与传统理论不同.假设活性种引发聚合后形成的大分子链不再反...

| Abstract: | Aiming at solving the several queries in the classic theory of the anionic polymerization,with the help of a self-invented device containing a spiral tubular reactor,the kinetics of the anionic bulk polymerization of styrene was investigated.Results showed that the polymerizations followed the classic theory of the anionic polymerization before 4% of the conversion.After that,however,there would appear a stationary-conversion platform and then a significant increase in polymerization rate.In order to explai... |
