Abstract
A resin composition for capstock, comprising 100 to 30 parts by weight of an impact resistance modifier having a multilayer structure, and 0 to 70 parts by weight of a methyl methacrylate (co)polymer containing 50 to 100% by weight of methyl methacrylate and 50 to 0% by weight of a monomer which is copolymerizable therewith, wherein the total amount of the impact resistance modifier and the methyl methacrylate (co)polymer is 100 parts by weight, wherein the outer layer of said impact resistance modifier and/or said methyl methacrylate copolymer is copolymerized with 0.5 to 40% by weight of a reactive monomer based on the total amount of the impact resistance modifier and the methyl methacrylate (co)polymer as a polymer component, and wherein the homopolymer of said reactive monomer has an SP value of 9.8 (cal/cm)/or more.
