ABSTRACT:
This method for preparing an acrylic-modified chlorinated polyolefin resin comprises graft-copolymerizing an acid-modified chlorinated polyolefin resin with a monomer mixture containing a (meth)acrylate ester monomer having one hydroxyl group and another vinyl monomer in the presence of a cyclic ether compound. Also, the cyclic ether compound may be added in an amount of 1 to 100 parts by weight based on 100 parts by weight of the acid-modified chlorinated ployolefin resin, and the cyclic ether compound may be dioxane and/or 1,3-dioxolane.
