Abstract:
A composition comprising, by weight,(a) a graft copolymer comprising a backbone of a propylene polymer material having graft polymerized thereto at least one vinyl monomer capable of being polymerized by free radicals, wherein the polymerized monomers are present in an amount of about 10 to about 120 parts per hundred parts of the propylene polymer material, and(b) an additive selected from the group consisting of (i) about 0.5% to about 10% of at least one low molecular weight ethylene polymer or a functionalized derivative thereof having a number average molecular weight of about 300 to about 5000, and (ii) a combination of about (1) 0.5% to about 10% of at least one of the low molecular weight ethylene polymers in (i) and (2) about 0.5% to about 10% of inorganic microspheres, based on the total weight of the composition.
