ABSTRACT:
Polymer blend compositions having an advantageous combination of low temperature toughness, solvent resistance, scratch resistance, paintability and elevated temperature resistance comprise from about 20 to about 65 weight percent of a rubber modified monovinylidene aromatic/ethylenically unsaturated nitrile/N-arylmaleimide copolymer and from about 35 to about 80 weight percent of certain selected polyester-based elastomeric thermoplastic polyurethane ingredients. The resulting polymer blend compositions are especially well suited for use in the preparation of molded articles or thermoformed sheet materials intended for use in relatively low temperature environments including, for example, in various motor vehicle and/or recreational vehicle applications, as freezer and refrigerator liners, snow removal equipment housings or accessories, and the like.
