<p>A methacrylic resin composition having excellent transparency, appearance, weatherability, gloss, impact resistance and processability, which comprises a methacrylic resin and a graft copolymer having a multilayer structure prepared by polymerizing a monomer component comprising an alkyl methacrylate such as methyl methacrylate as a main component in the presence of a chain transfer agent to form an innermost layer of a crosslinked methacrylic polymer, polymerizing a monomer component comprising an alkyl acrylate such as butyl acrylate as a main component in the presence of the innermost layer polymer to form an intermediate layer and subsequently polymerizing a monomer component comprising an alkyl methacrylate such as methyl methacrylate as a main component to form an outermost layer on the intermediate layer.</p> |
