摘要： The invention relates to polypropylene compositions, methods of preparing the polypropylene compositions, and methods of producing molded or extruded articles of the polypropylene composition. In one embodiment, the polypropylene composition contains: (a) about 60 to about 65 wt. % of a polypropylene resin; (b) about 10 to about 15 wt. % of an ethylene-alpha-olefin copolymer rubber; (c) about 20 to about 25 wt. % talc; (d) about 0.5 to about 3.0 wt. % of a grafted polypropylene resin; (e) about 0.2 to about 0.5 wt. % of an unsaturated fatty acid amide; and (f) about 0.2 to about 0.5 wt. % scratch-resistant agent, all based on the weight of the polypropylene composition. The scratch-resistant agent contains about 30 to about 50 wt. % of an ethylene vinyl acetate, and about 50 to about 70 wt. % of an aliphatic petroleum resin, based on the weight of the scratch-resistant agent. In another aspect, the invention relates to a process for preparing the polypropylene composition described above. In a further aspect, the invention involves a method of molding or extruding the polypropylene composition described above. In yet a further aspect, the invention includes molded or extruded articles of the polypropylene composition described above. The polypropylene compositions of the invention are especially useful in the preparation of molded objects and articles requiring superior scratch resistance.
