Resin composition of thermosetting resin and thermoplastic resin

Claim 1

A resin composition containing a homogenous mixture of Components (A), (B) and (C) wherein said composition comprises (1) Component (C) as a reactive diluent and resin components consisting of Components (A) and (B), or (2) resin components consisting of Components (A), (B) and (C), wherein a thermosetting resin is Component (A), a thermoplastic resin is Component (B), and at least one compound selected from the group consisting of an epoxy resin capable of dissolving the thermoplastic resin and a reactive diluent possessing at least one epoxy group is Component (C) in a ratio such that the proportions of Components (A), (B) and (C) fall respectively in the ranges of 30 to 85% by weight, 10 to 30% by weight, and 5 to 49% by weight, based on the total weight of the resin composition, wherein the weight ratio of Component (B) to Component (C) is from about 0.2 to about 2; and wherein said thermosetting resin as Component (A) is an epoxy resin selected from the group consisting of a bisphenol A epoxy resin, a urethane modified bisphenol A epoxy resin, a novolak epoxy resin, a cresol novolak epoxy resin, and a glycidyl amine epoxy resin; and wherein said thermoplastic resin as Component (B) is a resin selected from the group consisting of a polycarbonate, a polyether ketone, a polysulfone, a polyether sulfone, a polyether imide and an aromatic polyester; and wherein said at least one of the epoxy resin and the reactive diluent as Component (C) comprises at least one compound selected from the group consisting of glycidyl aniline, phenyl glycidyl ether, glycidyl ester epoxy resin, hexanediol diglycidyl ether, and polypropylene glycol glycidyl ether.
