PROBLEM TO BE SOLVED: To obtain a polymer composition which can realize a reduction in permanent compression set, can increase a crosslinking speed, and can improve productivity of a conductive roller, a conductive belt and the like. . SOLUTION: A crosslinking agent is added to a polymer composition mainly composed of a polymer having a carbon-carbon double bond and a halogen represented by an epichlorohydrin polymer such as an epichlorohydrin-ethylene oxide-allyl glycidyl ether copolymer. Thioureas such as sulfur and tetramethylthiourea. |
