Abstract: Impact toughness modified polymer mixtures containing, obtained from sulfur dioxide, vinyl aromatic compounds, unsaturated polar compounds (component A), and at least one polymeric rubber compound with an elastomer property profile (component B), optionally a thermoplastic polymer (component C), and processing aids, colorants, stabilizers, antioxidants, or strengthening materials (component D). Impact toughness modified polymer mixtures containing, obtained from sulfur dioxide (a1), vinyl aromatic compounds (a2), unsaturated polar compounds (a31), selected from compounds of formula (I): R = H or Me, R = CN, CHO, or COOR ; R = H or 1-20C alkyl, and/or cyclic olefins with unconjugated double bonds (a32), or nonpolar acyclic aliphatic olefin (a33) structured (sic) copolymerizate (component A), and at least one polymeric rubber compound with an elastomer property profile (component B), and optionally a thermoplastic polymer (component C), and processing aids, colorants, stabilizers, antioxidants, or strengthening materials (component D). An Independent claim is included for preparation of the polymer mixtures by mixing components (A) and (B) and optionally components (C) and (D) without previous melting, and melting and homogenization of the mixture obtained or mixing and melting of the components at increased temperature, and isolation of the product.
