PURPOSE:To obtain the titled composition easy to produce and of outstanding electrical conductivity, useful for tires and belts, by curing treatment of a composition comprising a hydroxyl group-contg. liquid diene polymer, polyisocyanate compound and specific polyacrylic fiber. CONSTITUTION:The objective composition can be obtained by curing treatment of a liquid polymer composition comprising (A) a hydroxyl group-contg. liquid diene polymer (pref. with a number-average molecular weight 500-10,000 and OH group content 0.3-7meq/g), (B) a polyisocyanate (e.g., liquid modified diphenylmethane diisocyanate), and (C) a polyacrylic fiber containing pref. 5-50pts. by wt. of copper with said metallic copper deposited thereon. The amount of the component C to be used is pref. 5-500pts. by wt. based on 100pts. by wt. of the component A.
