Abstract

A thermoplastic resin composition comprising (A) 1-90% by weight of a polyamide elastomer and (B) 99-10% by weight of at least one of the following (a) and (b): (a) a rubber-modified thermoplastic styrene resin consisting of a rubber-modified styrene polymer containing a hydroxyl group-containing alkenyl monomer as a copolymerized component or a mixture of rubber-modified styrene polymer with a styrene polymer, in which mixture at least one of these polymers contains a hydroxyl group-containing alkenyl monomer as a copolymerized component, (b) a mixture or reaction product of (1) 40-99% by weight of a thermoplastic polyurethane with (2) 60-1% by weight of a functional group-containing styrene resin in which a styrene resin is copolymerized with an unsaturated compound having at least one functional group selected from the group consisting of a carboxyl group, an acid anhydride group, an amino group, an epoxy group and a hydroxyl group. The above thermoplastic resin composition has a permanent antistatic property and is superior in mechanical properties, heat resistance during molding, moldability and surface appearance.
