(57) [Summary] (Modified) [Structure] At least one alkyl acrylate having an alkyl group having 1 to 12 carbon atoms, and at least one methacrylic acid having an alkyl group having 1 to 8 carbon atoms Alkyl esters, unsaturated monomers copolymerizable with these, 10 to 90 parts by weight of at least one polymer layer [A] having a Tg of 30 ° C. or lower, which is obtained by polymerizing a monomer mixture composed of a polyfunctional crosslinking monomer and a polyfunctional grafting monomer, It is a multi-layered polymer composed of a combination of 10 to 90 parts by weight of at least one polymer layer [B] having Tg of −20 to 50 ° C., and the outermost layer is the polymer layer [B]. [Effect] It is easy to mold, has good flexibility and bending durability at room temperature, and also has good transparency and excellent weather resistance, making it suitable for injection molded materials, sheets, films, tubes and other processed products. Optimal. |
