ABSTRACT:
This invention is a thermoplastic blend based on polycarbonate, thermoplastic polyurethane and an impact modifier. These resins have been found to be suitable for preparing molded or shaped articles having excellent combinations of processability, heat resistance, flexibility, solvent resistance and low temperature toughness. These resins comprise (a) about 35 to about 65 percent by weight of a thermoplastic aromatic polycarbonate; (b) about 35 to about 65 percent by weight of a thermoplastic polyurethane; and (c) about 1 to about 20 percent by weight of an impact modifier, which weight percentages are based on the combined weights of the polycarbonate and thermoplastic polyurethane. A preferred embodiment of the present invention is a thermoplastic automobile part, such as a bumper facia, prepared from such a thermoplastic resin.
