Abstract

The free carboxyl content of linear polyesters, e.g. those comprising at least 85 mol per cent of glycol or bisphenol terephthalate units, is reduced by adding to the polyester (after polymerization) a copper salt of a mono- or di-carboxylic acid providing 15-400 parts of Cu per million of polyester, and (at any stage) an alkali metal salt of an anion capable of reducing cupric ions to cuprous, the reducing anion being in molar excess of the Cu salt, and mixing the molten polyester and the additives until the free carboxyl content of the polyester is reduced. The polyester may derive in part from, e.g., adipic, sebacic, isophthalic, bibenzoic or hexahydroterephthalic acid. Suitable glycols are ethylene, tetramethylene, neoptentyl and 2,2 - dimethyl - 1,4 - butylene glycols, dimethylolcyclohexane, bis - p - (2 - hydroxyethyl)benzene, 4,41 - bis - (2 - hydroxyethoxy), diphenyl, 1,4 - dihydroxy[2,2,2]bicyclooctanebisphenol A, 2,2-bis(p-hydroxycyclohexyl)propane, 1,4 - cyclohexane diol, 4,41 - dihydroxybiphenyl and (bicyclohexyl)-4,41-dimethanol. Suitable copper salts are the acetate, benzoate, undecylenate, phthalate, stearate, propionate, butyrate, valerate, caproate, caprylate, palmitate, oleate, phenylacetate and terephthalate, and the reducing anion may be iodide, a phosphite, thiosulphate, sulphide, oxalate or formate.
