Abstract

"Procedure for preparing copolyesters of terephthalic acid", of high molecular weight, linear, containing sulfonate groups, and consisting of the structural elements of the general formula **(See formula)** wherein Ar means a phenylene moiety and X consists of 99-70 mole% of a straight or branched alkylene moiety with 2-20 carbon atoms, a cycloalkylene moiety, or the moiety of general formula **(See formula)** where R is a straight or branched chain alkylene moiety with 1-10 carbon atoms, and at 1-30 mol% of a moiety containing sulfonate groups of the general formula **(See formula)** wherein M stands for a metal, the terephthalic acid copolyester having relative viscosities in solution η rel in the region of 1.1-4.0 (measured in a solution of 1 g of substance in 100 cc of m -cresol at 25ºC); by melt condensation of components containing sulfonate groups, ester formers, together with a terephthalic acid derivative and a grisol, the acid derivatives and the glisols being used in approximately equivalent amounts; characterized in that a derivative of a dicarboxylic moiety, of general formula, is reacted **(See formula)** wherein Ar is a phenylene moiety and R1 is hydrogen or a 1-10 carbon atom straight or branched chain alkyl moiety with a diol derivative of the general formula R2-O-X-O-R2 where X means a straight or branched chain alkylene moiety with 2-20 carbon atoms, a cycloalkylene moiety, the moiety of general formula **(See formula)** wherein R is a straight or branched chain alkylene moiety with 1-10 carbon atoms and R2 is hydrogen, an aliphatic or aromatic moiety, and a derivative of a diol of the general formula **(See formula)** where M means a metal and R2 has the meaning indicated above; at temperatures of 150 - 300ºC, excluding humidity and oxygen in an inert gas atmosphere, at pressures between normal pressure and 0.001 Torr, using catalysts for polycondensation in fusion, and using in such proportions that the amount of salt of 2 -sulfonate-methylpropanediol- (1, 3) condensed is in the zone between 1 and 30 moles based on the amount of condensed glycols.
