ABSTRACT:
Provided is an electroconductive resin composition made of:
(a) about 100 parts by weight of a polyphenylene ether or a mixture of a polyphenylene ether and a styrene resin having a weight ratio of polyphenylene ether:styrene resin of less than 100:0 to greater than about 5:95;
(b) about 1 to about 50 parts by weight of a carboxylic acid amide wax having a high softening point;
(c) about 5 to about 35 parts by weight of a carbon black having a dibutylphthalate adsorption of about 70 ml/100 gm or more;
(d) optionally 0 to about 50 parts by weight of a rubber material;
(e) optionally 0 to about 50 parts by weight of an electroconductive inorganic filler;
(f) optionally 0 to about 20 parts by weight of a polyolefin resin; and
(g) optionally 0 to about 30 parts by weight of a non-electroconductive inorganic filler. Also provided are an antistatic coating and a molded article made from the resin composition.
