ABSTRACT:
A thermosetting resin composition comprising compounds (A) an alkenyl-substituted nadimide, (B) a compound having at least one vinyl group or cyclic olefin, or both and (C) a phenol resin, and optionally (D) at least one polymerization catalyst selected from the group consisting of organic peroxides, onium salts, and cationic catalysts is disclosed. The components contained in the composition exhibit excellent compatibility among them. The cured product obtained from the thermosetting resin composition has superior anti-hygroscopicity and toughness, without impairing excellent heat resistance, electrical characteristics, mechanical strength, and small molding shrinkage inherently possessed by alkenyl-substituted nadimide resin. The composition is useful not only as a laminating material, a casting material, a molding material, a coating material, a paint, an adhesive, a sealing material, etc., but also as a matrix resin for composite materials.
