PURPOSE: To provide the composition comprising a polyamideimide elastomer, a polycarbonate resin, a styrenic resin and an electrolyte in a specific ratio, excellent in conductivity, heat resistance and mechanical characteristics, and having permanent antistaticity.
CONSTITUTION: This composition comprises (A) a polyamideimide elastomer, (B) a polycarbonate resin (preferably a resin produced from bisphenol A as a raw material), (C) a styrenic resin (preferably polybutadiene, styrene-butadiene copolymer), and (D) an electrolyte selected from organic eletrolytes and inorganic eletrolytes (preferably an organic eletrolyte such as a sodium alkylbenzene sulfonate), the amounts of the component A and C being 1-90 pts.wt. and 0.01-10 pts.wt., respectively, per 100 pts.wt. of the total amount of the components B and C. The component A is preferably obtained from caprolactam, a tribasic or tetrabasic polycarboxylic acid and polyoxyalkyleneglycol.
