| 摘 要： | 综述了脂肪族聚酯改性制备生物降解性聚酯的研究进展.在聚酯中引入刚性链段(即将脂肪族聚酯与芳香族、液晶基元共聚合)可改善聚酯的加工性能;在聚酯中引入亲水基大分子(即将脂肪族聚酯淀粉共混或与聚乙二醇共聚合)可改善聚酯的亲水性能.今后脂肪族聚酯改性研究的重点将解决功能化基团的引入、合成路线的简化、成本的降低及改性的效果等方面的问题.

| Abstract: | This paper reviewed the recent developments in studies on biodegradable polyesters prepared via modification of aliphatic polyesters, The processability of polyesters could be improved significantly after incorporating stiff chain segment through copolymerization of aliphatic polyester with aromatic liquid crystal element, The hydrophilicity of polyesters could be raised after introducing macromolecular hydrophilic radical via copolymerization of aliphatic polyester starch with polyethylene glycol. The future studies on modification of aliphatic polyesters would be focused on developing the technologies for introducing functionalized group, simplifying synthetic route, reducing cost and improving modification effectiveness. |
