The present invention relates to an acrylic impact modifier, a method for preparing the same, and a vinyl chloride resin composition including the same. More particularly, in the manufacture of a core-shell structured impact modifier, a living radical ATRP (Atom Transfer Radical Polymerization) is produced during core preparation. The polymerization reaction monomers are added together to emulsion polymerization to introduce an ATRP (Atom Transfer Radical Polymerization) reaction site on the core surface, and then, by living radical ATRP polymerization reaction only at the initiation reaction site on the core surface. The present invention relates to an acrylic impact modifier, a method for preparing the same, and a vinyl chloride resin composition including the same, the method including manufacturing a shell surrounding the core by growing a polymer having an average molecular weight of 2,000 to 50,000.n n n The acrylic impact modifier according to the present invention and the vinyl chloride resin composition including the same have an effect of improving impact resistance, agglomeration properties, and workability. |
