Abstract:
    The present invention provides a toughened cycloaliphatic epoxy resin composition comprising (a) a curable aromatic or cycloaliphatic epoxy resin, (b) a monohydroxylated epoxidized polydiene polymer which comprises at least two polymerizable ethenically unsaturated hydrocarbon monomers wherein at least one is a diene monomer which yields unsaturation suitable for epoxidation, and wherein the polymer contains from 0.5 to 7 milliequivalents of epoxy per gram of polymer, and (c) a curing agent.
