Abstract

An epoxy resin composition comprises a polyepoxide containing on the average more than one epoxide group per molecule, and a mixture of the isomers of tetrahydrophthalic anhydride which is liquid at ambient temperature. The isomeric mixture is prepared by heating tetrahydrophthalic anhydride derived from butadiene and maleic anhydride in the presence of an acidic catalyst (see Group IV(b)). Polyepoxides specified are:-the diepoxides of vinylcyclohexenes, butadiene, dicyclopentadiene, and dicyclopentenyl ether, the diglycidyl ethers of bisphenol A and of ethylene glycol, 6-methyl-3,4-epoxy-cyclohexylmethyl-6-methyl-3,4-epoxy cyclohexane-1-carboxylate, and 3(3,4-epoxy-cyclohexyl)-8,9-epoxy-2,4-dioxa-spiro(5:5)-undecane: the polyepoxides may be mixed. Catalysts specified are SnCl4 and benzyldimethylamine; and ethylene glycol may also be added. Specification 795,378 is referred to.ALSO:Tetrahydrophthalic anhydride (m.pt. 100 DEG C.), made in known manner from butadiene and maleic anhydride, is isomerised by heating in the presence of an acidic catalyst to form mixtures (of the four possible isomers) having melting point of e.g. 17 DEG -46 DEG C. In Example (1) 100 g. of tetrahydrophthalic anhydride were heated at 250 DEG C. in the presence of 1 g. of P2O5 are then distilled at 4 mm. Hg.; the heating period varied from 0.5-1.25 hours. Specification 795,378 is referred to.
