Abstract

Higgly crystalline copolyester mouldings based on polyteramethylene terephthalate are mfrd. by (trans)esterifying a dibasic acid component comprising >=90 mol.% tetephthalic acid or an ester-forming deriv. thereof and =10 mole.% 4-10C aliph. diacid acid or ester-forming derivs. with a diol component comprising >=90 mole % butanediol-1,4 and up to 10 mole % some other 2-10C aliph. diol or 8-12C cycloaliph. diol, in presence of 0.05-2.0 mole % based on the dibasic acid, of a tri- or higher-functional cpd. (I) and polycondensing the react. prod. in know manner. (I) may be penetaerythritol, trimethylolpropane, trimellitic acid. Prods. have superior rate and degree of crystallisation.
