摘　　要：脂肪族聚酯是最重要的一类可生物降解聚合物,其合成过程中多采用含金属元素的催化剂,残留的金属元素会对其生物相容性和环境相容性造成不利的影响,因而,采用无毒的非金属催化剂成为脂肪族聚酯合成中备受关注的课题。本文对非金属催化剂催化合成脂肪族聚酯的研究进展进行综述。Aliphatic Polyesters are the most important and the most widely applied biodegradable polymers. They are usually synthesized via ring opening polymerization or polycondensation catalyzed by metallic catalysts, especially in in- dustrial production. The metallic residue contaminates the product and does harm to its biocompatibility when used as biomaterials or to its environmental compatibility when used as commodity polymers, Therefore, synthesizing aliphatic polyesters using nontoxic nonmetallic catalysts have attracted much attention recently. This article reviews recent progress in synthesis of biodegradable aliphatic polyesters in the presence of nonmetallic catalysts,
