DMS与BDO酯交换法制备PBS的聚合工艺探索

Study on Polymerization Technique of Preparing PBS from DMS and BDO by Transesterification

以DMS和BDO为原料,采用酯交换法制备了高分子量的PBS,研究了制备PBS的最佳工艺条件和最佳工艺的物料性能。采用吹膜及注塑工艺制备了PBS薄膜和样条,得到最佳工艺的样条性能。

PBS with high molecular weight was prepared from DMS and BDO by transesterification,the optimal conditions and material performance for the preparation of PBS were studied.PBS film and spline were prepared by blowing film and injection molding,the best p rocess spline performance was obtianed.
