Highly thermally conductive thermoplastic resin composition, and a method of producing highly thermally conductive thermoplastic resin

摘要

PROBLEM TO BE SOLVED: To provide a thermoplastic resin composition excellent in thermal conductivity, maintaining such high thermal conductivity without blending a large amount of a high thermal conductive inorganic compound, and capable of being injection molded even when a general purpose mold for injection molding is used.SOLUTION: A thermoplastic resin composition mainly includes a thermoplastic resin of which a main chain has a repeating unit structure represented by general formula (1), where Aris a trivalent aromatic residue obtained by removing three carboxyl groups from an aromatic tricarboxylic acid, Sp is a bivalent straight substituent which may have a branch having 2 to 20 carbon atoms in the main chain, Aris a substituent selected from the group consisting of an aromatic group, a condensed aromatic group, a heterocyclic group, an alicyclic group and a cycloaliphatic and heterocyclic group, and an inorganic filler.
