ABSTRACT:
A curable laminate epoxy composition comprising (a) an epoxy resin; (b) an amphiphilic block copolymer containing at least one epoxy resin miscible block segment and at least one epoxy resin immiscible block segment; wherein the immiscible block segment comprises at least one polyether structure provided that the polyether structure of said immiscible block segment contains at least one or more alkylene oxide monomer units having at least four carbon atoms; such that when the epoxy resin composition is cured, the toughness of the resulting cured epoxy resin composition is increased; (c) a curing agent; and (d) a curing catalyst. The amphiphilic block copolymer is preferably an all polyether block copolymer such as a PEO-PBO diblock copolymer or a PEO-PBO-PEO triblock copolymer.
