中文摘要：
可生物降解高分子材料在医药工业中的应用越来越广泛，聚丙交酯和聚碳酸酯是其中最典型的代表。开发新型、高效催化剂，制备各种微观结构和性能和用途不同的该类可生物降解材料是目前高分子化学研究领域的重要课题。迄今，研究最多的催化剂是过渡金属铝、锌、镉、钴等配合物，而有关稀土配合物的报道较少。本课题设计、合成了一系列新型含氮、氧、磷杂原子的多齿配体螯合稀土烷基、胺基、酚氧基等配合物。研究表明其中的非手性双酚配位稀土烷基配合物，可催化外消旋丙交酯杂同选择聚合，提出了配体空间效应决定选择性的点控制机理；在此基础上合成了立体结构可控的三臂、四臂聚丙交酯；通过调解配体上取代基的空间和电子效应及引发基团如稀土-碳键、稀土-氧键及稀土-氮键，实现了非茂稀土配合物催化环氧烷与二氧化碳的共聚合及环碳酸酯的开环聚合，这是迄今聚合活性最高的单组分稀土催化剂；研究了稀土催化环碳酸酯聚合过程中聚合物双峰分布的机理；开发了C2对称结构的苯基双亚胺稀土氯配合物，实现了对共轭双烯烃的高顺1,4-选择性聚合，在此基础上通过增加配体的刚性和给电子性，首次实现了共轭双烯烃与可生物降解己内酯的嵌段共聚合。
