微量活性引发剂促进惰性引发剂引发环氧乙烷的开环聚合速率研究

Study on the Promoting Effect of Trace Amount of Active Initiator on the Rate of Ring-opening Polymerization of Ethylene Oxide with an Inert Initiator

研究了利用微量更活泼的阴离子引发剂促进具引发惰性的磺胺嘧啶钠引发环氧乙烷开环聚合的反应速度,作了系列比较,并讨论了其影响速率的机制。

Adding a trace amount of active initiator into the inert initiator SF-Na, the rate of ring-opening polymerization of ethylene oxide was promoted. The promoting mechanism was discussed.
