Abstract: A polymer composition with improved scratch and mar resistance contains (1) 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, and (2) an additive selected from the group consisting of (a) about 0.5% to about 10% of at least one low molecular weight ethylene polymer or a functionalized derivative thereof, and (b) a combination of (i) about 0.5% to about 10% of at least one of the low molecular weight ethylene polymers in (a) and (ii) about 0.5% to about 10% of inorganic microspheres, based on the total weight of the composition. Optionally the composition can also contain a compatibilizing agent such as an unsaturated carboxylic acid-functionalized propylene polymer material. The composition can optionally contain about 2% to about 30% of one or more rubber components, about 15% to about 50% of a broad molecular weight distribution propylene polymer material, or a combination of the two.

Abstract: A polyolefin nanocomposite is prepared by melt blending (a) a polyolefin and (b) a smectite clay in the presence of at least one intercalating agent that is a solid at room temperature and is selected from the group consisting of (a) hydroxy-substituted carboxylic acid esters, (b) amides, (c) hydroxy- substituted amides, and (d) oxidized polyolefins, wherein the ratio of the intercalating agent to the clay is at least 1:3, based on the ash content of the clay.
