Abstract

A linear copolyester is derived from a glycol of formula HO(CH2)nOH, where n is 2-6, terephthalic acid, isophthalic acid and at least one pair of acyclic dicarboxylic in the molar ratio 0.5 to 2.0 and each having the formula HOOC-CH2-X-CH2-COOH where X is a divalent radical containing in the chain of atoms linking the two -CH2-COOH groups 2 to 8 atoms of which not more than 2 atoms are oxygen atoms and the rest are hydrocarbon carbon atoms and having from 0 to 3 hydrocarbon carbon atoms in side-chain substituents, the acyclic dicarboxylic acids of said pair (or each pair if there be more than one) differing from one another by at least 3 atoms in the chain of atoms linking the -CH2-COOH groups, the molar proportions of the acid components of said copolyester being within the following ranges: terephthalic acid 20 to 60 per cent, isophthalic acid 15 to 50 per cent and acyclic dicarboxylic acids 10 to 50 per cent. The copolyesters are made by the melt polymerization of a mixture of bis-(hydroxyalkyl esters of the acids. They are used as adhesives for joining a lamina of a polyalkylene terephthalate to another lamina (see Group VIII) or as a binding agent for a mat of non-woven fibres or as an adhesive for replacing solder in fabricating metal containers. To this end they may be used dissolved in a solvent (e.g. butyrolactone, benzyl alcohol, dimethyl sulphoxide, dioxane, dimethyl formamide, diacetone alcohol, chloroform, cyclohexane, methyl ethyl ketone preferably in admixture with toluene or dioxane, methylene chloride, nitromethane, tetrahydrofurane, toluene or carbitol acetate) or admixed with a plasticizer (e.g. chlorinated diphenyl or an alkyl or aryl phosphate). In examples copolyesters were prepared by polycondensing the bis-(hydroxyethyl) esters of terephthalic, isophthalic, adipic and sebacic acids in presence of ethylene glycol and antimony oxide; the bis-(hydroxyethyl) esters of terephthalic, isophthalic and sebacic acids being prepared by reacting the dimethyl esters of the acids with ethylene glycol in presence of calcium acetate and the bis-(hydroxyethyl) ester of adipic acid being prepared by reacting the free acid with ethylene glycol. Specification 578,079, [Group IV], is referred to.
