Abstract:
    The present invention provides a toughened epoxy resin composition comprising: (a) a curable aromatic and/or a curable cycloaliphatic epoxy resin, (b) an epoxidized low viscosity polydiene polymer wherein the polymer contains at most in the range of from 1.0 to 7.0 milliequivalents of epoxy per gram of polymer, and (c) a curing agent. Certain novel epoxidized low viscosity polydiene polymers are also described.
