Abstract
A new Zn alkoxide catalyst supported by an N-heterocyclic carbene rapidly polymerizes D,L-lactide (D,L-LA) to heterotactic enriched poly(lactide)(PLA), while the free carbene and analogs instead yield highly isotactic enriched PLA.
摘要
一种由氮杂环卡宾负载的新型锌醇盐催化剂能迅速将D,L-丙交酯（D,L-LA）聚合成富含间同立构的聚丙交酯（PLA），而游离卡宾及其类似物则生成富含全同立构的PLA。
