VINYL CHLORIDE RESIN COMPOSITION AND MOLDED ARTICLES MADE THEREOF

摘要

A vinyl chloride resin composition having excellent weatherability and impact resistance which comprises (a) a vinyl chloride resin, (b) a graft copolymer which is obtained by graft-polymerizing (b2) a graft monomer component composed of 40 to 100 % by weight of methyl methacrylate and 0 to 60 % by weight of at least one monomer selected from the group consisting of an alkyl acrylate, an alkyl methacrylate, an unsaturated nitrile and an aromatic vinyl compound onto (b1) a crosslinked elastomeric polymer composed mainly of an alkyl acrylate, the methyl ethyl ketone-soluble portion of the graft copolymer having an .eta.qsp/c of 1 to 5 measured at 30.degree.C with respect to its 0.2g/ 100cc acetone solution, and (c) calcium carbonate; and molded articles having a multilayer structure wherein a layer molded from the above composition is used as the surface layer or the inner layer.
