Abstract

Poly(butylene adipate-co-terephthalate) is a well-known aliphatic-aromatic biodegradable random co-polyester that is structurally composed of a chemical unit of butylene adipate and butylene terephthalate. It can be synthesized by a polycondensation reaction in the melt stage. However, the synthesis process is very much complicated because it requires a high esterification temperature as well as a vacuum to achieve a suitable molecular weight for different grade industrial applications. Additionally, the synthesis process gives the various side reactions that associate depolymerization with hydrolytic degradation, the color of polymer, tetrahydrofuran formation, etc. This short literature review deals with the various methods development of poly(butylene adipate-co-terephthalate) synthesis for commercial scale. Moreover, different grades of its synthesis are also investigated with chain extenders, branching agents, chemical functionalization and in-situ incorporation of nanocomposites.

聚（己二酸丁二醇酯-共对苯二甲酸酯）聚酯合成工艺及产品开发

摘要

聚（亚丁基己二酸酯共-terephthalate）是一种公知的脂肪族-芳族可生物降解的随机在结构上由己二酸丁二醇酯和对苯二甲酸丁二醇酯的化学单元的共聚酯。它可以通过熔融阶段的缩聚反应合成。然而，合成过程非常复杂，因为它需要较高的酯化温度和真空度才能获得适合不同等级工业应用的分子量。另外，在合成过程给出了各种副反应副解聚与水解降解，聚合物的颜色，四氢呋喃形成等与聚的各种方法发展此短文献综述优惠（亚丁基己二酸酯共-对苯二甲酸酯）合成商业规模。此外，还使用扩链剂、支化剂、化学功能化和纳米复合材料的原位掺入研究了不同等级的合成。
