Abstract
The addition of a compound containing an aliphatically unsaturated bond as a storage stability improver to a hydrosilylating addition reaction type hardenable electrically-conductive composition comprising at least one alkenyl group-containing isobutylene polymer which can undergo hydrosilylation reaction per molecule and an electrical conductivity-providing material makes it possible to obtain an electrically-conductive composition having an excellent storage stability at high temperatures. Further, the use of such an electrically-conductive composition makes it possible to provide an electrically-conductive roller having an excellent productivity and processability and an excellent stability of electrical properties against environmental change.
