ABSTRACT:
One of the objects of the present invention is to produce a shaped article of a cured resin having well-balanced heat resistance and toughness by using a plural liquid pack type heat-curable resinous composition of a low liquid viscosity and excellent handling property with good storage stability. As claimed in the present invention, individual components comprising a polyisocyanate compound (a), a radically polymerizable unsaturated monomer compound bearing no functional group reactive with isocyanate, for example, styrene or a (meth)acrylic acid derivative (b), a polyol compound bearing no radically polymerizable unsaturated bond such as a polyether polyol (c), a radical catalyst (e) and a ring-forming catalyst (d) are separated into 2 liquid packs or 3 liquid packs, and they are mixed on molding, fed into the mold, and reaction-cured in the mold to give a shaped article of a cured resin of excellent heat resistance, toughness and other properties.
