Abstract
Copolyesters are made by (a) heating a mixture of a diaryl terephthalate and/or isophthalate (100 mol. per cent), a diaryl ester of carbonic or oxalic acid (0-10 mol per cent) and a dihydric phenol (at least 100 mol per cent) until the melt viscosity of the mixture is at least 2000 poises, (b) adding to the reaction product at least 15% by weight, calculated on the polyester which should theoretically derive from (a) of a linear polyester of terephthalic and/or isophthalic acid and a diprimary alcohol and having a viscosity number of 0.1 to 0.5 and (c) continuing the polycondensation at an elevated temperature. Specified dihydric phenols are resorcinol, hydroquinone and bisphenol A whilst specified dihydric alcohols are ethylene glycol and other polymethylene glycols, 2:2-dimethyl - 1:3 - propanediol, dimethylol cyclohexanes, di-, tri-, tetra- and penta-ethylene glycol and hydroxyethylation products of resorcinol, hydroquinone and bisphenol A.
