Thermoplastic elastomer composition with excellent wear resistance

摘要

The present invention relates to a thermoplastic elastomer composition with excellent wear resistance comprising: (A) 1 to 50 parts by weight of a rubber-reinforced thermoplastic resin obtained by graft-polymerizing (a) 80 to 20 parts by weight of an aromatic vinyl monomer or a mixture of an aromatic vinyl monomer and other vinyl monomer copolymerizable therewith in the presence of (b) 20 to 80 parts by weight of a rubber-like polymer, said rubber-reinforced thermoplastic resin having a graft ratio of 5 to 300%, the intrinsic viscosity ( eta ) of the ungrafted moiety being 0.05 to 3.0 dl/g as measured in 30 DEG C methylethyl ketone, and the total weight of (a) and (b) being 100 parts by weight; and (B) 99 to 50 parts by weight of a thermoplastic elastomer, the total weight of (A) and (B) being 100 parts by weight.
