摘　　要：聚己内酯及聚交酯是可供生物降解的高分子材料,具有良好的生物相容性和优异的力学性能,广泛应用在生物医学领域,可应用于骨骼固定材料、手术缝合线、药物载体和组织修复材料等。本文综述了不同类型含氧配体螯合金属铝络合物以配位-插入机理引发环酯开环聚合近年来的研究成果。Polycaprolactone（PCL） and Polylactic acid（PLA） as biodegradable alternative polymers had excellent biodegradable,mechanical and physical properties.PCL and PLA were widely used in the area of biomedicine as bone stabilization,surgical sutures or as a delivery medium for controlled release of drugs or scaffolds for tissue engineering,etc.The systematic studies of recent years were presented including ring-opening polymerisation catalyzed by oranoaluminium complexes bearing oxygen ligands with the coordination-insertion mechanism.
