摘要

PROBLEM TO BE SOLVED: To provide an ethylene-based polymer for producing an abrasion-resistant resin molding which is excellent in abrasion resistance measured by a sand/rubber wheel abrasion test and further excellent in the balance between moldability and heat resistance.SOLUTION: An ethylene-based polymer for producing an abrasion-resistant resin molding satisfies the following (1) to (5). (1) Is either an ethylene homopolymer or a copolymer of ethylene and a 3-20C -olefin. (2) Is polymerized using a single-site catalyst. (3) Has a weight-average molecular weight Mw of 300,000 to less than 1,000,000. (4) Has a melting point Tm of 130°C to lower than 135°C. (5) Has a sand/rubber wheel abrasion test performance of 0.035-0.24 cmas measured for a sample fabricated from the ethylene-based polymer.
