Abstract
PURPOSE: A small amount of a graft polymer resulting from multi-stage polymerization of methyl methacrylate and aromatic vinyl compound in the presence of an acrylic elastomer is incorporated to vinyl chloride resins, thereby improving impact strength without any adverse effect on the surface luster, transparency and weathering resistance.
CONSTITUTION: An acrylic elastomer (A) is prepared by using (A1) 50W70 wt% of an acrylic ester, (A2) 50W30 wt% of an aromatic vinyl compound, wherein the total of (A1) and (A2) is 100 parts by wt, and (A3) 0.1W3 parts of a polyfunctional crosslinking agent having one or more allyl groups in the molecule, in which first emulsion polymerization of a mixture of components A2 and A3 is conducted and then component A1 and A3 are polymerized in the presence of the resulting polymer latex. As the second process, two-stage polymerization of 30W80 wt% of methyl methacrylate and 70W20 wt% of an aromatic vinyl compound, wherein the total is 70W20 parts by wt, is conducted in the presence of 30W80 parts of acrylic elastomer (A) to form graft polymer (B). Compositions of vinyl chloride resin are incorporated with 0.1W3 wt% of graft copolymer B.
