ABSTRACT:
Directly paintable polymer compositions contain (1) a thermoplastic olefin, (2) a maleic anhydride-grafted propylene homopolymer or random copolymer, (3) a maleic anhydride-grafted olefin polymer material, (4) a functionalized polymer that reacts with the maleic anhydride groups of the grafted polymers, and, optionally, (5) a maleic anhydride-grafted ethylene polymer. The amount of (2)+(3) or (2)+(3)+(5) is at least 16 parts but less than 27 parts per hundred parts of the thermoplastic olefin.
