摘要：
Low-crystallization-speed polyesters obtained by means of the polycondensation of terephthalic acid with at least one (C.sub.2 -C.sub.10)-(Cyclo)alkylene glycol in the presence of 2-50 mol % of a copolymerizable reactant of general formula:ROOC-Ar-OOC-Ar'-COO-Ar-COOR (I)wherein Ar and Ar' stand for aromatic radicals, and R stands for a hydrogen atom or a (C.sub.1 -C.sub.4)-alkyl radical, or the OR group is replaced by a halogen.
