摘　　要：脂肪族聚碳酸酯(APC)是一类新型可生物降解高分子材料,具有良好的生物降解性能、生物相容性和力学性能。综述了APC的制备方法,包括光气法、CO2/环氧化物共聚法、开环聚合法和酯交换法,并重点阐述了酯交换法的研究进展;分析了APC的热力学性能、结晶行为、力学性能、热降解机理和生物降解性能与结构的关系;介绍了APC的应用情况。对APC未来的研发方向及实现工业应用进行了展望。Aliphatic polycarbonates（APC） as a kind of new biodegradable polymers have favorable biodegradability,biocompatibility and mechanical properties. The synthetic methods for APC,namely reaction of diol with phosgene,ring-opening polymerization,copolymerization of epoxides with carbon dioxide and transesterification of dialkyl carbonate with diol,were reviewed in this article. Furthermore,the relationships of their structure and thermal properties,crystallization behavior,mechanical properties,thermal degradation mechanism as well as biodegradation behavior were introduced.
