Patent ID: 7338623

Claim:
An electrically-conductive resin composition for molding consisting essentially of (A) a thermoplastic resin and (B) an electrically-conductive polymer blended together, wherein said electrically-conductive polymer is an electrically-conductive polyester doped with a dissociable inorganic salt, and said doped polyester is a comb polyester having one or more polyester chains each having a weight average molecular weight of from 50,000 to 200,000 and having been obtained by subjecting a lactone to ring-opening polymerization in the presence of a trifunctional or higher functional, polyhydric alcohol as a polymerization initiator, wherein said polyhydric alcohol is selected from the group consisting of glycerin, trimethylolpropane, hexanetriol, diglycerin, pentaerythritol, sorbitol, sucrose, partially-saponified polyvinyl alcohols, acrylic polyols, polybutadinepolyols, and ethylene oxide adducts thereof.
