The present invention is applied to an engineering plastic such as polycarbonate (PC), polycarbonate / polybutylene terephthalate alloy resin, or a thermoplastic resin such as polyvinyl chloride resin to give excellent impact resistance and colorability. An impact modifier comprising: a) a seed obtained by emulsion copolymerizing a vinyl monomer and a hydrophilic monomer; b) a rubbery core surrounding the seed and containing an alkyl acrylate polymer having 2 to 8 carbon atoms in the alkyl group; And c) an acrylic impact modifier having a multilayer structure comprising a shell surrounding the rubbery core and containing an alkyl methacrylate polymer having 1 to 4 carbon atoms of an alkyl group, a method of manufacturing the same, and a thermoplastic resin containing the same. do. |
