Chemically different cyclic ester oligomers can be copolymerized to form copolyesters whose properties can be tailored by the choice of cyclic ester oligomers used. The copolyesters formed are especially useful as encapsulants and as coatings. In many instances the copolyesters, assuming they are not randomized in later transesterification reactions, have unique microstructures related to the sequencing of repeat units the their polymer chains.
(ZH) 化学性质上不同的环酯低聚物可以共聚形成共聚聚酯,这种共聚聚酯的性能可以通过选择所使用的环酯低聚物而进行设计。形成的共聚聚酯尤其可用作密封剂和涂层。在许多情况下,共聚聚酯,假定它们在后面的酯交换反应中没有被无规化,具有独特的与其聚合物链重复单元的序列有关的微观结构。
