Abstract

There is a need for high-performance applications for terephthalic acid (TPA) polyesters with high heat resistance, impact toughness, and optical clarity. Bisphenol A (BPA) based polycarbonates and polyarylates have such properties, but BPA is an endocrine disruptor. Therefore, new TPA polyesters that are less hazardous to health and the environment are becoming popular. Tetramethylcyclobutanediol (TMCD) is a difunctional monomer that can be polymerized with TPA and other diols to yield copolyesters with superior properties to conventional TPA polyesters. It has a cyclobutyl ring that makes it more rigid than cyclohexanedimethanol (CHDM) and EG. Thus, TMCD containing TPA copolyesters can have high heat resistance and impact strength. TPA can be made from abundantly available upcycled polyethylene terephthalate (PET). Therefore, this review discusses the synthesis of monomers and copolyesters, the impact of diol composition on material properties, molecular weight, effects of photodegradation, health safety, and substitution of cyclobutane diols for future polyesters.

摘要

需要具有高热稳定性、抗冲击韧性和光学透明性的对苯二甲酸 (TPA) 聚酯的高性能应用。双酚 A (BPA) 基聚碳酸酯和聚芳酯具有这些特性，但 BPA 是一种内分泌干扰物。因此，对健康和环境危害较小的新型 TPA 聚酯越来越受欢迎。四甲基环丁烷二醇 (TMCD) 是一种二官能单体，可与 TPA 和其他二醇聚合，得到性能优于传统 TPA 聚酯的共聚酯。它具有一个环丁基环，使其比环己烷二甲醇 (CHDM) 和 EG 更具刚性。因此，含有 TMCD 的 TPA 共聚酯可以具有高热稳定性和抗冲击强度。TPA 可以由丰富的可回收利用的聚对苯二甲酸乙二醇酯 (PET) 制成。因此，本综述讨论了单体和共聚酯的合成、二醇组成对材料性能的影响、分子量、光降解的影响、健康安全性以及环丁烷二醇的替代，以用于未来的聚酯。
