Wear resistant resin composition

A wear resistant resin composition comprising:

• (A) 100 parts by weight of a modified microblend obtained by bonding an organic acid group to a microblend consisting of 1 to 70 wt % of polypropylene and 99 to 30 wt % of a propylene-ethylene random copolymer consisting of 15 to 50 mol % of an ethylene polymer unit and 85 to 50 mol % of a propylene polymer unit, or a mixture of the microblend and the modified microblend, the concentration of the organic acid group in the modified microblend or the mixture being 0.01 to 1 mmol based on 1 g of the microblend, and the microblend containing 10 to 90 wt % of a component eluting at a temperature of −40 to +30° C. based on the total of all the eluting components fractionated by temperature rise elution fractionation using o-dibromobenzene as a solvent;
• and
• (B) 1 to 1,000 parts by weight of at least one filler which is ionically crosslinkable and is selected from the group consisting of a fibrous filler and a lamellar filler, and the resin composition containing a gel in an amount of 10 to 80 wt % and having a flexural modulus of 2,000 MPa or less.
