Japanese Patent JP7006136
Kind Code:
B2
Abstract:
To provide a rubber crosslinked product having excellent compression set resistance, obtained by using a cyclopentene ring-opened polymer.SOLUTION: A rubber crosslinked product is obtained by cross-linking a polymer composition containing 20-200 pts.wt. of carbon black with respect to 100 pts.wt. of a rubber component containing a cyclopentene ring-opened polymer having a branched structure. After the rubber crosslinked product in a 25% compression state is held at 100°C for 72 hours, the rubber crosslinked product shows a permanent compression set of 35% or less.SELECTED DRAWING: None
