摘　　要：综述了从可再生资源开发生物基聚酯以取代石油基聚酯的新策略,即利用新型生物基单体,尤其是生物基环状单体对聚对苯二甲酸酯进行化学共聚改性,重点介绍了生物基环状聚酯的合成、性质及应用方向,讨论了特殊环状结构对聚合物的热力学性能及生物降解性能的影响,指明了生物基环状聚酯在包装、涂层、智能材料等不同领域的潜在应用前景。The new strategy of developing bio-based polyesters from renewable resources to replace petrochemical-based polyesters is reviewed,that is,using new bio-based monomers,especially bio-based cyclic monomers to modify polyterephthalates by chemical copolymerization.The synthesis,properties and application direction of bio-based cyclic polyesters are emphatically introduced.The effects of special cyclic structures on the thermodynamic properties and biodegradability of polymers are discussed,and the potential applications of bio-based cyclic polyesters in different fields including packaging,coating and intelligent materials are pointed out.
