Abstract
A thermoplastic resin composition comprising a melt mixed product of (A) 70% to 98% by weight of at least one thermoplastic resin selected from the group consisting of polyamides, polyacetals, polyesters, and polycarbonates and (B) 30% to 2% by weight of ultra-high molecular weight polyolefin powder having an intrinsic viscosity [.eta.] of 10 dl/g or more, measured in decalin at 135.degree. C., and having an average particle size of 80 .mu.m or less and having a particle size distribution such that substantially all of the powder particles pass through a sieve having a sieve number of 100 and at least 20% by weight of the total powder particles pass through a sieve having a sieve number of 350. This thermoplastic resin composition has excellent abrasion resistance, excellent impact resistance, and a high critical PV value.
