Abstract

PURPOSE: An epoxy resin improved with regard to deterioration of working circumstance and of ability of the cured product, which is prepared by compounding a low styrene-maleic acid polymer prepared in a specified manner with an epoxy resin.
CONSTITUTION: A low styrene-maleic acid polymer (A), obtained by the reaction of (i) an α-alkyl-substituted styrene-containing styrene with (ii) a maleic acid, in a mol ratio of (i) to (ii) of 1W5 in the absence of a radical polymerization catalyst under the reflux of an unreactive organic solvent of b.p. ≥130°C, is compounded with an epoxy resin (B) having at least two epoxy groups in one molecule, in such a proportion that at least 0.5 of the acid anhydride group or carboxyl group in said low polymer (A) is contained for every epoxy group in the epoxy resin. The organic solvent of b.p. ≥130°C is preferably an aromatic solvent such as xylene, cumene, cymene or chlorobenzene.
