中文百科

聚酯

聚酯(Polyester)是一类在其主链上含有酯基官能团的聚合物。虽然聚酯有很多种,但是“聚酯”一词通常指的是聚对苯二甲酸乙二酯(PET)。

聚酯包括天然化合物如植物角质,以及通过逐步缩合而成的合成纤维如聚碳酸酯和聚(对苯二甲酸/己二酸)乙二酯。天然聚酯和一部分合成聚酯是可以生物降解的,但绝大部分合成聚酯都不会被生物降解。

聚酯可分为「饱和聚酯」和「不饱和聚酯」两大类,通常由一种或多种多元酸(酸酐)与一种或多种多元醇经缩聚制得。

Stretching polyester fabric
Transesterification: An alcohol-terminated oligomer and an ester-terminated oligomer condense to form an ester linkage, with loss of an alcohol. R and R' are the two oligomer chains, R'' is a sacrificial unit such as a methyl group (methanol is the byproduct of the esterification reaction).

Polyester is a category of polymers that contain the ester functional group in their main chain. As a specific material, it most commonly refers to a type called polyethylene terephthalate (PET). Polyesters include naturally occurring chemicals, such as in the cutin of plant cuticles, as well as synthetics through step-growth polymerization such as polybutyrate. Natural polyesters and a few synthetic ones are biodegradable, but most synthetic polyesters are not. This material is used very widely in clothing.
