Disclosed is a composition comprising, by weight, (a) about 94% to about 30% of a graft copolymer comprising a backbone of a propylene polymer material having graft polymerized thereto monomers that form grafted copolymers or terpolymers, th e monomers being selected frorn the group consisting of (i) styrene and acrylo nitrile, and (ii) styrene and maleic anhydride, or alpha-methylstyrene, styrene and maleic anh ydride, wherein the grafted copolymers or terpolymers formed from (i) or (ii) are pr esent in an amount of about 10 to about 95 pph of propylene polymer material, (b) about 5% to about 40% of at least one aromatic polycarbonate, and (c) about 1% to about 15% of at least one aliphatic polyester. The composition optionally also comprises about 5% to a bout 20% of one or more rubber components, about 1% to about 50% of a propylene polymer material, or both.
