Title:
RADICAL CURABLE RESIN COMPOSITION, FIBER-REINFORCED MOLDING MATERIAL, AND MOLDED ARTICLE USING SAME
Document Type and Number:
WIPO Patent Application WO/2021/261196
Kind Code:
A1
Abstract:
Provided is a radical curable resin composition comprising, as essential raw materials, a vinylester resin (A), an unsaturated monomer (B) having a flash point of at least 100ºC, a polyisocyanate (C), a polymerization initiator (D), a stabilizer (E), and a polymerization inhibitor (F), the composition being characterized in that the stabilizer (E) is a nitroxy radical and the polymerization inhibitor (F) is at least one compound represented by formula (1) or (2). This radical curable resin composition has excellent handleability, flexibility, and curability during molding, has a small change over time in curability during molding, and has excellent storage stability. Therefore, this radical curable resin composition can be suitably used for a molding material and a molded article thereof. (In formulae (1) and (2), R1 represents a hydrogen atom or a C1-C4 alkyl group, and X1 and X2 each independently represent a hydrogen atom, a C1-C4 alkyl group, a hydroxyl group, or a methoxy group.)
