Abstract

Highly polymeric linear esters of the kind obtainable by heating glycols of the series HO(CH2)nOH, where n is an integer greater than one but not exceeding 10, with terephthalic acid or with an ester-forming derivative of the acid, are stabilized by incorporating with the reactants, or with the low molecular weight product formed, a monofunctional compound which is a relatively non-volatile acid such as benzoic, phenoxyacetic or stearic acids, or ester-forming derivatives of these acids, a relatively non-volatile alcohol such as benzyl alcohol or an aliphatic alcohol containing more than 9 carbon atoms or their carboxylic acid esters, conveniently the terephthalic acid esters. In the examples, dimethyl terephthalate and ethylene glycol are reacted in the presence of (1) ethylene glycol; (2) ethyl benzoate; (3) ethylene glycol dibenzoate; (4) ethylene glycol stearate; (5) cetyl terephthalate; (6) cetyl alcohol, and in example (7) terephthalic acid, ethylene glycol and benzoic acid are heated. Other monofunctional compounds are specified in the Provisional Specification.
