Abstract
Highly transparent, impact-resistant molded articles can be produced from a molding composition, comprising: (1) a major portion of polyvinyl chloride or a copolymer comprising at least 70% by weight of vinyl chloride units; and (2) an amount effective to impart impact resistance of: (a) at least one homopolymer of an acrylate monomer having the formula ##STR1## wherein R is a straight-chain or branched alkylene residue of 3-8 carbon atoms, optionally interrupted by 1-2 ether oxygen atoms, wherein the straight-chain portion of said alkylene residue contains at least 3 carbon atoms; or (b) a copolymer of said acrylate monomer and up to 30% by weight of at least one acrylate ester of a C.sub.4-12 aliphatic alcohol.

A modified polyvinyl chloride molding composition, comprising (1) a major proportion of polyvinyl chloride or a copolymer comprising at least 70% by weight of vinyl chloride units;
- and (2) an amount effective to impart impact resistance and high transparency of (a) at least one homopolymer of an acrylate monomer having the formula ##STR6## wherein R is a straight-chain or branched alkylene residue of 3-8 carbon atoms, optionally interrupted by 1-2 ether oxygen atoms, wherein the straight-chain portion of said alkylene residue contains at least 3 carbon atoms;
- or (b) a copylymer of said acrylate monomer and up to 30% by weight of at least one acrylate ester of a C.sub.4-12 aliphatic alcohol.
