摘　　要：聚对苯二甲酸乙二酯 (PET)是由对苯二甲酸 (TPA) (或对苯二甲酸二甲酯 (DMT) )与乙二醇 (EG)缩聚而成的。如果在PET的生产中用 1,4环己二甲醇 (CHDM )部分取代EG ,经共缩聚所得聚酯即为CHDM改性PET的ET/CT共聚酯。本文概述了ET/CT共聚酯的研发现状、制备。Poly(ethylene terephthalate) is synthesized from dimethyl terephthalate(DMT) and ethylene glycol(EG) by melt polycondensation. If EG is partially substituted by 1,4-cyclohexynol (CHDM) during PET production, the resulted ET/CT copolyester is poly(ethylene terephthalate-co-1,4-cyclohexylene dimethylene terephthalate) which is modified by CHDM. The preparation, properties and applications of ET/CT copolyester were summarized.
