PURPOSE:To obtain the title composition improved in conductivity, moldability and heat (aging) resistance by mixing a polyphenylene ether resin with two specified block copolymers and conductive carbon. CONSTITUTION:100 pts.wt. mixture comprising 10-99wt.% polyphenylene resin having a number-average molecular weight of 1000-100000 and at least 0.01 terminal ring group of the formula [wherein R1 to R5 are each H, (substituted) alkyl, halogen or (substituted) aryl; and R6 to R9 are each R1, (substituted) alkenyl, alkoxy, N-lactarm or the like)] on the average per 100 phenylene ether units, 90-1wt.% block copolymer comprising 50-90wt.% vinylaromatic compound polymer blocks (A) and olefin compound polymer blocks (B) and having a degree of unsaturation of 20% or below, and 0-10wt.% block copolymer comprising 20-50wt.% component A and component B having a degree of unsaturation of 20% or below is mixed with 3-40 pts.wt. conductive carbon. |
