<p>PURPOSE:To obtain the title composition improved in conductivity, heat resistance and moldability by mixing a polyphenylene ether resin with a specified block copolymer. and conductive carbon. CONSTITUTION:3-40 pts.wt. conductive carbon is added to 100 pts.wt. total of 10-98wt.% polyphenylene ether resin of a number-average molecular weight (Mn) of 1000-100000, 89-1wt.% block copolymer comprising at least 50wt.% vinylaromatic polymer blocks and at most 90wt.% olefin compound polymer blocks of a degree of unsaturation of 20% or below and having an Mn of 2000-500000 and a molecular weight distribution of 1.05-10, and 1-10 pts.wt. block copolymer comprising 20-50wt.% vinylaromatic compound polymer blocks and 80-50wt.% olefin compound polymer blocks of a degree of unsaturation of 20% or below and having an Mn of 2000-500000 and a molecular weight distribution of 1.05-10.</p> |
