改性脂肪族聚酯的生物降解性研究
Biodegradation of Modified Aliphatic Polyester
【摘要】 以芳香二元酸为聚丁二酸丁二醇酯的共聚组分 ,合成了一系列聚丁二酸丁二醇酯 (PTS)共聚物 ,用土埋法和二氧化碳释放法测定其生物降解性 ,发现一定比例的共聚酯具有良好的生物降解性。
【Abstract】 A series of modified PTSs was synthesized by introducing an aromatic diacid unit into the chain of Poly(tetramethylene succinate)(PTS). The biodegradation of PTSs was studied by soil burial and CO 2 release test. A modified polyester with good biodegradability was obtained by changing the mole ratio of aromatic diacid.
