摘要
评述了碳正离子聚合的特点及其可控性研究进展过程。引发体系形成的离子对的平衡状态及适当亲核性试剂或电子对供体的存在对稳定系统碳正离子、促进链引发和链增长、抑制链转移、提高聚合可控性起着关键性作用。
The characteristics and research devel- opment of controlled carbocationic polymerization were discussed. The equillibrium state of the ion pair generated in initiator system and suitable nucle- ophilic reagent or electron pair donor in the system played a key role in the stabilization of carbocationicions, the promotion of chain initiation and chain propagation, the inhibition of chain transfer and the improvement of polymerization controllability.
