Abstract
A conductive polysulfone resin composition which has excellent processability and is prepared by mixing (A) 100 parts by weight of a composition essentially consisting of from 5 to 95% by weight of an aromatic polysulfone resin and from 95 to 5% by weight of a polyphenylene sulfide resin with (B) from 3 to 40 parts by weight of conductive carbon, is provided by the present invention; and molded articles having excellent electrical conductivity, heat resistance and mechanical strength, for example, a high-heat-resistant, conductive semi-conductor-chip-carrier can be prepared from the composition by injection molding and other processing methods.
