聚丁二酸丁二醇酯合成方法比较研究

The Comparison Study on Synthesis Methods of Poly(Butylenes Succinate)

以丁二酸、丁二醇为原料,用熔融缩聚法、溶液熔融相结合法两种不同方法合成聚丁二酸丁二醇酯(PBS)。通过对合成方法及合成结果的讨论,比较不同方法之间存在的区别,并分析了溶液熔融相结合方法的优势所在。

Poly （butylenes succinate） （PBS） with higher relative molecular weight was synthesized by succinic acid （SA） and 1, 4-butanediol （BD） .PBS have been synthesized by two methods, which were sotution poly-condensation melt poly-condensation and melt poly-condensation. This article compared the advantages of solution poly-condensation combined with melt poly-condensation and got a conclusion.
