Abstract

1,135,233. Poly (glycol terephthalates). COURTAULDS Ltd. 7 April, 1966 [12 April, 1965; 3 Dec., 1965], Nos. 15358/65 and 51356/65. Heading C3R. In the manufacture of fibre-forming polyesters by (a) effecting an esterification or ester-interchange reaction between a polymethylene glycol containing 2 to 10 carbon atoms and terephthalic acid or an ester thereof and (b) polycondensing the resulting polymethylene glycol terephthalate or low polymer thereof, the esterification or ester-interchange catalyst used is a mixture of a manganous salt and a cobaltous salt, preferably a mixture of manganous acetate and cobaltous acetate. The same catalyst mixture may also serve as the polycondensation catalyst, but preferably an antimony compound (e.g. antimony oxide) is added before polycondensation. A stabilizer (e.g. triphenyl phosphite or triphenyl phosphate) may be included in the polycondensation stage. Examples describe the manufacture of polyethylene terephthalate from ethylene glycol and terephthalic acid.
