Abstract

1,273,918. Transparent thermoplastic copolyesters. FARBWEKKE HOECHST A.G. 10 Aug., 1970 [9 Aug., 1969], No. 38369/70. Heading C3R. A non-crystalline, transparent, thermoplastic, linear polyester having a second-order transition temperature above 100‹ C. comprises units derived from terephthalic and 4,4<SP>1</SP>-diphenylsulphone dicarboxylic acids, ethylene glycol and 1,4-dimethylol cyclohexane. Preferably terephthalic acid comprises 15-85 mol per cent of the acid units and ethylene glycol comprises 20-80 mol per cent of the diol units.
