ABSTRACT:
A vinyl chloride resin composition having improved weather resistance and impact resistance which contains, as a modifier, a graft copolymer which is prepared by graft-polymerizing 50 to 15 parts by weight of a monomer component composed of mainly methyl methacrylate on 50 to 85 parts by weight of a cross-linked alkyl acrylate polymer so that 30 to 90% by weight of the monomer component is graft-polymerized and, then, the remaining portion of the monomer component is graft-polymerized in the presence of 0.1 to 5% by weight, based on the whole amount of the monomer component, of a copolymerizable cross-linking agent, the fraction extracted from said graft polymer with methyl ethyl ketone having a specific viscosity of at least 0.6 as measured in a concentration of 0.1 g/100 cc in acetone at 30.degree. C. The composition has a reduced die swelling and provides shaped articles having excellent weather resistance and impact strength.
