NOVELTY - A radically polymerizable resin composition contains (meth)acryloyl group-containing polyurethane (A) (I), (meth)acryloyl group-containing polyurethane (B) (II), and radically polymerizable unsaturated monomer (C).    USE - Radically polymerizable resin composition is used for molding material for forming molded article e.g. carbon fiber-reinforced plastic, pipe, container and blade for wind power generation (all claimed). Uses include but are not limited to motor vehicle outer plate, platform component for vehicles, boat, personal watercraft, rail vehicle component, aircraft component, building material for antiseismic reinforcement, industrial robot and sheet molding compound.    ADVANTAGE - The radically polymerizable resin composition has excellent hardenability and low viscosity. The molded article formed using radically polymerizable resin composition has excellent elongation rate, mechanical strength, toughness and heat resistance.    DETAILED DESCRIPTION - A radically polymerizable resin composition contains (meth)acryloyl group-containing polyurethane (A) of formula: X-C(=O)-NH-T-NH-C(=O)-O-Y'-O-C(=O)-NH-T-NH-C(=O)-X (I), (meth)acryloyl group-containing polyurethane (B) of formula: X-C(=O)-NH-T'-NH-C(=O)-O-Y"-O-C(=O)-NH-T'-NH-C(=O)-X (II), and radically polymerizable unsaturated monomer (C).    Y'=aliphatic cyclic structure containing alkylene;    T= aliphatic cyclic structure containing alkylene or chain alkylene;    X=atom group containing (meth)acryloyl;    Y"=structure having polyether structure having 2C or more oxyalkylene unit;and    T'=aromatic structure-containing compound, aliphatic cyclic structure containing alkylene or chain alkyelne group.    INDEPENDENT CLAIMS are included for the following:    (1) molding material or molded article, which is obtained using radically polymerizable resin composition, reinforcing fiber material (D) and organic peroxide (E); and    (2) carbon fiber-reinforced plastic, which is obtained by hardening the molding material.
