Patent ID: 7342084

Claim:
A peroxidically crosslinked hydrogenated vinylpolybutadiene, having compression set values in the range from a) 0 to 14% at 23° C./70 h, b) 0 to 19% at 100° C./70 h, c) 0 to 20% at 125° C./70 h, and d) 0 to 28% at 150° C./70 h; and compressive stress relaxation values in the range from e) 0 to 10% at 23° C./24 h, f) 0 to 12% at 23° C./72 h, and g) 0 to 15% at 23° C./168 h; and said peroxidically crosslinked hydrogenated vinylpolybutadiene being formed by crosslinking a hydrogenated vinylpolybutadiene via a peroxide, said hydrogenated vinylpolybutadiene having a degree of hydrogenation in the range from 85 to 96.2%.
