PURPOSE:To produce a conductive resin compsn. excellent in mechanical properties, moldability, and surface smoothness by compounding a specific thermoplastic copolycarbonate resin, a thermoplastic polyester resin, and a conductive carbon black. CONSTITUTION:The title compsn. is obtd. by compounding 100 pts.wt. resin component comprising 99-60wt.% thermoplastic coplycarbonate resin consisting of 0.1-50wt.% siloxane structural units of formula I and 99.9-50wt.% structural units of formula II and 1-40wt.% thermoplastic polyester resin with 0.1-30 pts.wt. conductive carbon black. In these formulas, R<1> is 2-6C alkylene or alkylidene; R<2> and R<3> and each 1-3C alkyl or (substd.) pheny1; n is 1-200; A is 1-10C linear, branched, or cyclic alkylidene, aryl-substd. alkylidene, arylenedialkylidene, -O-, -S-, -CO-, or -SO2-; and R<4>, R<5>, R<6>, and R<7> are each H, halogen, 1-4C alkyl, or alkenyl. |
