摘要
脂肪族聚酯由于其生物降解性和经济性，已成为国内外降解材料研究的重点。以丁二酸和丁二醇为原料，通过熔融缩聚法合成聚丁二酸丁二醇酯（PBS），并通过与己内酯、聚乙二醇共聚，改善其降解性能。利用FT-IR、^1H-NMR、DSC、粘度法测定分子量等方法对共聚物组成、热学性能及亲水性能进行了研究。实验结果表明，改性后的聚酯高分子链有更好的柔韧性和亲水性，可以加快降解速率。
Aliphatic polyesters have excellent biodegradability and is very economical in use, therefore it is looked as one of the general acknowledged research directions of degradable materials. In this paper poly（butylenes succinate）（PBS） were synthesized through a transesterification/polycondensation process from succinic acid, 1, 4-butanediol, and the copolymers were synthesized from poly（butylene succinate）, ε-caprolactone, poly（ethylene glycol）. The physical properties and structure characterization of the copolymers were tested with infrared spectroscopy（IR）, nuclear magnetic resonance spectroscopy （^1H-NMR）, differential scanning calorimetry（DSC）, thermogravimetry（TG） and viscosity analysis. The results indicated that the modified aliphatic polyester have been improved in flexibility and hydrophilicity, and the degradation rate can be improved.
