| titleOfInvention | Preparation of semiconductive roll |
| abstract | PURPOSE:To efficiently prepare a semiconductive roll having a stable electric resistance level by using a semiconductive polymer composition wherein a polymeric compound having an ether bond in the repeating unit thereof is used as a matrix and perchlorate is compounded with said matrix in a specific amount. CONSTITUTION:A semiconductive polymer composition wherein a polymeric compound having an ether bond in the repeating unit thereof is used as a matrix and perchlorate is contained in the matrix is used as a material for forming the semiconductive polymer layer 2 of a semiconductive roll. Perchlorate is compounded in an amount of 0.1 - 50pts.wt. per 100pts.wt. of the matrix component. Said polymer composition is prepared as a powdery mixture by sufficiently kneading perchlorate with the polymeric compound being the matrix component. A metal shaft body 1 is arranged to the recessed part 4 having a semicircular cross-section of a lower mold 6 and, after molds 5, 6 are clamped, the semiconductive polymer composition is injected in the molds 5, 6 under high pressure and this pressure is held for a predetermined time. The molds 5, 6 are cooled to solidify the polymer composition in the molds and the semiconductive roll is obtained. No perchlorate is exuded from the semiconductive polymer composition in the molds at the time of injection molding and the inner peripheral surface of the molds are not contaminated. |
