Abstract

In the manufacture of polyethylene terephthalate by (a) effecting an esterification or esterinterchange reaction between terephthalic acid or a dialkyl ester thereof and (b) polycondensing the product, zinc chloride or manganous chloride is used as a catalyst for the polycondensation reaction and also, possibly, for the esterification or ester-interchange reaction. Additional catalysts may also be used, e.g. titanium compounds of formula Ti(OR)4, where R is an alkyl, aryl, aralkyl, acyl, aroyl or hydroxyalkyl group; also silicic acid, caustic potash, sodium carbonate, tetraethyl ammonium hydroxide, calcium acetate, cobaltous acetate or cobaltous chloride. Reaction may also be effected in the presence of titanium dioxide, carbon black, phthalocyanine pigments or the usual phosphorous compounds, e.g. trimethyl phosphate, triethyl phosphate, triphenyl phosphite, phosphoric acid or phosphorous acid. Up to 20 mol. per cent of the terephthalic component may be replaced by another dicarboxylic acid and up to 20 mol. per cent of the ethylene glycol may be replaced by other glycols or thioglycols. Hydroxyacids may also be included as copolymerizable components. Examples describe the manufacture of polyesters by reacting (i) dimethyl terephthalate and ethylene glycol, with or without the addition of bis-(2-hydroxyethyl) adipate or bis-(2-hydroxyethyl isophthalate or (ii) terephthalic acid and ethylene glycol, with or without isophthalic acid.
