Abstract

The invention relates to a process for producing neopentyl-glycol based polyesters in the presence of an organotitanium catalyst whereby a polyol component comprising neopentyl glycol and a polyacid component comprising isophthalic and/or terephthalic acid are added gradually to a reactor maintained at a temperature of 230 to 330 DEG C.
