Claims
- 1. 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.
- 2. A radical copolymerizable unsaturated resin composition according to claim 1, wherein the radical copolymerizable unsaturated resin is an unsaturated polyester.
- 3. A molding material comprising the radical copolymerizable unsaturated resin composition of claim 1.
- 4. A molded article comprising the molding material of claim 3.
- 5. A radical copolymerizable unsaturated resin composition according to claim 1, wherein the radical copolymerizable unsaturated resin is an unsaturated polyester.
- 6. A radical copolymerizable unsaturated resin composition according to claim 1, wherein the principal chain (A1) comprises 70-99.9% by weight of the styrene repeat units and 0.1-30% by weight of other unsaturated repeat units including the (meth)acrylate repeat units.
- 7. A radical copolymerizable unsaturated resin composition according to claim 1, wherein the side chain (A2) comprises oxyethylene units in an amount within a range of 60-100% by weight.
- 8. A radical copolymerizable unsaturated resin composition according to claim 1, wherein the amount of the graft copolymer (A) is within a range of 0.5-3 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.
