Abstract
An object of the present invention is to provide a polypropylene resin composition that is blended in a polyolefin resin to improve its surface characteristics and impart sustained water repellency and yet is low in aggregates so as not to deteriorate the visual appearance, a polyolefin resin composition containing the polypropylene resin composition, and a molded article of the polyolefin resin composition. A composition that achieves the object is a polypropylene resin composition obtained by heating and kneading a material containing (A) a polypropylene resin, (B) a polypropylene wax, (C) a polyorganosiloxane containing at least one silicon-atom-bonded alkenyl group in each molecule, and (D) an organic peroxide.
