Abstract:
A radical copolymerizable unsaturated resin composition comprisinga compatibilizing agent, an addition polymerized polymer (D) for low profile, a radical copolymerizable unsaturated resin, and a polymerizable unsaturated monomer, wherein the compatibilizing agent is a graft copolymer (A) which contains styrene repeat units as a principal component, said graft copolymer (A) having: a principal chain (A1) that is a copolymer comprising (meth)acrylate repeat units and the styrene repeat units; and a side chain (A2) selected from a ring-opening polymerized polyether side chain consisting of a polyoxyalkylene ether, a polyester side chain, and a polycarbonate side chain, the side chain (A2) being bonded to the principal chain (A1), the weight ratio (A1/A2) of a principal chain (A1) to a side chain (A2) is within a range of 65/35-20/80, and the amount of the graft copolymer (A) being within a range of 0.1-10 parts by weight based on the total of the amount of the radical copolymerizable unsaturated resin and the amount of the addition polymerized polymer as 100 parts by weight.
