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.
