POLYCARBONATE RESIN COMPOSITION

PROBLEM TO BE SOLVED: To provide a polycarbonate resin compsn. excellent in antistatic properties by incorporating a polycarbonate resin having a specified viscosity average mol.wt., a certain copolymer contg. a rubbery polymer, a polyetheresteramide block copolymer, and a metal salt into the same. SOLUTION: A polycarbonate resin (A) having a viscosity average mol.wt. of 10,000-100,000, a copolymer (B) (e.g. an ABS resin) formed from an arom, vinyl monomer, a vinyl cyanide monomer, and a rubbery polymer, a polyetheresteramide block copolymer (C), and potassium diphenylsulfone-3- sulfonate (D) are mixed to give a mixture comprising 30-96wt.% ingredient A, 1-50wt.% ingredient B, 1-30wt.% ingredient C, and 0.01-2.0wt.% ingredient D. A polycarbonate resin compsn. of the invention is prepd. by melt mixing, kneading, and extruding the above-obtd. mixture with 1-50wt.% (based on the compsn.: the same applies hereunder) copolymer (e.g. a styrene-acrylonitrile copolymer) having a number average mol.wt. of 15,000-200,000, 1-50wt.% inorg. or org. filler, and 1-30wt.% phosphoric ester compd. with a twin-screw extruder, etc.
