ABSTRACT:
Polyblends comprising a thermoplastic vinyl chloride polymer and a thermoplastic copolymer of (1) at least one vinyl aromatic monomer, (2) acrylic acid or methacrylic acid, or both, and (3) optionally at least one additional copolymerizable termonomer have useful properties, notably useful heat deflection temperatures under load. The copolymers are preferably rubber-modified graft copolymers.
