聚丁二酸丁二醇酯(PBS)制备工艺技术

Preparation Technology of PBS

摘要: 聚丁二酸丁二醇酯(PBS)一般由丁二醇和丁二酸缩聚而得，是典型的可完全降解聚合物材料。本技术采用预缩聚反应和终缩聚反应逐步聚合的新型工艺，该工艺技术包含五大部分：即浆液预制、酯化反应过程、预缩聚反应过程、终缩聚反应过程、干燥过程，该技术工艺流程简单，生产的产品质量标准高、聚合度较高、相对分子质量大，可极大地减低制作成本。

Abstract: Polybutylene succinate (PBS) is generally obtained by polycondensation of butanediol and succinic acid and is a typical fully degradable polymer material. The technology adopts a novel process of gradual polymerization of pre-polycondensation reaction and final polycondensation reaction, and the process technology comprises five parts: slurry pre-fabrication, esterification reaction process, pre-polycondensation reaction process, final polycondensation reaction process, drying process. This technology has simple process, high product quality standard, high polymerization degree and large relative molecular weight, which can greatly reduce the production cost.
