摘要：
The present invention pertains to a master batch composition which contains 10 to 95% by mass of an additive for plastics, 1 to 50% by mass of an olefin polymer having specific physical properties, and 1 to 89% by mass of a polyolefin resin as a carrier, which is useful for producing a polyolefin resin, particularly an injection molded product of a polypropylene resin, which can improve dispersibility of additives in the polyolefin molded product, which permits high density filling of various additives in the master batch composition, and which is free of blocking. The present invention is also directed to a polyolefin resin composition in which the master batch composition is compounded in a polyolefin resin, and to a polyolefin molded product using the resin composition.
