    • Disclosed is a non-rigid vinyl chloride polymer composition comprising 100 weight parts of a vinyl chloride polymer resin, 5-50 weight parts of a graft copolymer modifier and 10-300 weight parts of a plasticizer. The graft copolymer modifier is obtained by graft-polymerizing 25-150 weight parts of an alkyl ester of methacrylic acid having 1 to 4 carbon atoms in the alkyl group or a monomer mixture composed of at least more than 50% by weight of said alkyl ester of methacrylic acid onto 100 weight parts of an acrylic elastomer having a swelling degree of 5 to 25 so that the grafting ratio is not larger than 50%. The acrylic elastomer is obtained by polymerizing a mixture comprising an alkyl ester of acrylic acid having 2 to 10 carbon atoms in the alkyl group or a monomer mixture composed of at least 50% by weight of said alkyl ester of acrylic acid, and a polyfunctional crosslinking agent. The non-rigid vinyl chloride polymer composition has excellent weatherability and impact resistance, and exhibits a good molding processability.
