    摘要： Provided are a propylene resin composition comprising 100 parts byweight in total of two different types of propylene polymers each having specific properties, from 0 to 50 parts by weight of a specific elastomer, and from 0 to 50 parts by weight of an inorganic filler; and a method for producing it. The production method comprises melting and kneading two polymer groups each comprising one or more propylene polymers. The resin composition in which the viscosity difference between the propylene homopolymer segments to form the base polymer and the amorphous propylene segments to form the disperse phase is small is produced by first melting and kneading one polymer group, then immediately adding the other polymer group thereto, and further kneading and melting the two. For the composition in which the viscosity difference therebetween is large, the polymer groups are separately kneaded in melt, and the resulting melts are further kneaded. The propylene resin composition has high stiffness, high impact resistance and high fluidity, and its moldings have good appearances.
