Abstract

1285904 Polycondensation catalyst for the production of polyesters KANEGAFUCHI BOSEKI KK and SNIA VISCOSA SOC NAZIONALE INDUSTRIA APPLICAZIONI VISCOSA SpA 25 Nov 1969 [25 Nov 1968] 57658/69 Heading C3R Polyesters are produced using as a polycondensation catalyst a mixture of metallic antimony and metallic titanium. Zinc acetate and triethyl phosphate or triphenyl phosphite may be used as catalysts in an esterification step to produce the esters for the polycondensation reaction. In the examples polyesters were made be polycondensing ethylene glycol and dimethyl terephthalate or mixtures thereof with dimethyl isophthalate or by polycondensing methyl p-(#- hydroxyethoxy) benzoate.
