摘要:
Polyesters with a high crystallization rate synthesized by the polycondensation of terephthalic acid with at least one C.sub.2 -C.sub.4 alkylenic glycol in the presence of 0.1-1.5 mol % of a copolymerizable reagent having the general formula:ROOC--Ar--OOC--Ar'--COO--Ar--COORwhere Ar and Ar'represent aromatic radicals and R represent a halogen, a hydrogen atom or a C.sub.1- C.sub.4 alkyl radical.
