摘要：
The present invention relates to an acrylic impact modifier having a multilayered structure, which offers both superior impact resistance and coloring characteristics to engineering plastics, such as polycarbonate (PC) and a polycarbonate/polybutylene terephthalate alloy resin, or to a polyvinyl chloride resin. The present invention provides an acrylic impact modifier having a multilayered structure comprising: a) a seed prepared by emulsion copolymerization of a vinylic monomer and a hydrophilic monomer; b) a rubbery core surrounding the seed and comprising a C2 to C8 alkyl acrylate polymer, and c) a shell surrounding the rubbery core and comprising a C1, to C4 alkyl methacrylate polymer, a method for preparing the same, and a thermoplastic resin comprising the same.
