The polypropylene and, optionally the homogeneously branched linear ethylene polymer, ethylene-propylene monomer rubber, ethylene-propylene-diene monomer rubber, heterogeneously branched linear ethylene polymer, and styrene block copolymer are grafted with an unsaturated organic compound containing at least one site of ethylenic unsaturation and at least one carbonyl group, e.g. maleic anhydride. The compositions exhibit excellent paintability with conventional paints without prior application of a primer or surface treatment, good heat resistance, good low temperature impact resistance, and they can be recycled by melt blending the compositions with thermoplastic materials, e.g., in an extruder.
