摘要：Polymer blend compositions having an advantageous combination of lowtemperature toughness, solvent resistance, scratch resistance and paintability containfrom 19 to 64 weight percent of a mass, solution, mass/suspension or mass/solutionpolymerized rubber modified monovinylidene aromatic/ethylenically unsaturated nitrilepolymer; from 35 to 80 weight percent of certain selected polyester-based elastomericthermoplastic polyurethane ingredients; and from 1 to 30 weight percent of a relativelyhigh rubber content emulsion polymerized rubber modified graft copolymer ingredient.The resulting polymer blend compositions are especially well suited for use in thepreparation of molded articles intended for use in relatively low temperature
environments including, for example, in various motor vehicle and/or recreational vehicleapplications, as freezer and refrigerator liners, snow removal equipment housings oraccessories.
