To designate the epichlorohydrin - ethylene oxide - allyl glycidyl ether copolymer which is

摘要

PPROBLEM TO BE SOLVED: To provide a polymer composition capable of realizing the reduction of compression permanent strain, increasing the crosslinking speed, and improving the productivity of an electroconductive roller, an electroconductive belt, etc. PSOLUTION: This polymer composition is prepared by compounding, as a crosslinking agent, sulfur and a thiourea such as tetramethyl thiourea to a polymer composition mainly composed of a polymer having a halogen and a carbon/carbon double bond represented by an epichlorohydrin polymer such as epichlorohydrin/ethylene oxide/an allylglicidyl ether copolymer, etc. PCOPYRIGHT: (C)2003,JPO
