摘要聚丙交酯是一类可生物降解的脂肪族聚酯,而且降解产物无毒。丙交酯开环聚合是合成聚丙交酯的一种方便的方法。在无水无氧的条件下,参照文献合成了两种三苄基稀土配合物,它们可以有效地催化L-丙交酯的开环聚合,中心金属离子半径对催化效果有一定影响,并通过对齐聚物末端基的分析,得出了开环聚合物的机理与文献报道一致。 Polylactide （PI,A）, an aliphatic pnlyesler, can be biodegraded after use, and its metabolite is low toxic. The preferred method for PIA production is ring-opening polymerization （ROP） of lactide, a process initiated by metal nph,xes. Two homolepli（. Iris（o-dimelhylaminobenzyl） complexes have been prepared with rigorous exclusion of air and moisture using standard Sehlenk techniques according t0 the melhods provided in lileralure. They can be used as efficient calalysts for ring-opening polymerization of lactid.
