Abstract

1,153,935. Polyalkylene terephthalates. FMC CORP. 5 Oct., 1967 [4 Nov., 1966; 7 Nov., 1966; 15 Nov., 1966], No. 45442/67. Heading C3R In a process for making polyalkylene terephthalates by effecting an esterification or ester-interchange reaction between an alkylene glycol and terephthalic acid or a dialkyl terephthalate and polycondensing the resulting reaction product, antimony oxalate or antimony oxysulphide is used as the polycondensation catalyst. Suitable esterification catalysts are calcium acetate and triethylamine while suitable ester-interchange catalysts are lithium hydride and zinc acetate.
