Abstract
Official abstract text for this publication.
A crosslinked rubber is a member for use in an environment at −10° C. or less produced by crosslinking a polymer composition containing 20 to 200 parts by weight of carbon black with respect to 100 parts by weight of a rubber component containing a monocyclic olefin ring-opening polymer having a proportion of cis bond of a structural unit derived from a monocyclic olefin of 45 to 95%.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method comprising producing a product with a crosslinked rubber as a member for use in an environment at −10° C. or less, the crosslinked rubber being produced by crosslinking a polymer composition containing 100 parts by weight of a rubber component containing a monocyclic olefin ring-opening polymer having a proportion of cis bond of a structural unit derived from a monocyclic olefin of 45 to 95% and 20 to 200 parts by weight of carbon black. 2. The method according to claim 1 , wherein the monocyclic olefin ring-opening polymer is a polymer consisting only of a structural unit derived from a monocyclic monoolefin or a copolymer comprising a structural unit derived from a monocyclic monoolefin and a structural unit derived from a monomer copolymerizable with the monocyclic monoolefin. 3. The method according to claim 1 , wherein the monocyclic olefin ring-opening polymer is a polymer consisting only of a structural unit derived from cyclopentene or a copolymer comprising a structural unit derived from cyclopentene and a structural unit derived from a monomer copolymerizable with cyclopentene. 4. The method according to claim 1 , wherein the content of the monocyclic olefin ring-opening polymer in the rubber component is 50% by weight or more with respect to 100% by weight of the total rubber component. 5. The method according to claim 1 , wherein the monocyclic olefin ring-opening polymer has a modifying group containing an atom selected from the group consisting of atoms in Group XV of the Periodic Table, atoms in Group XVI of the Periodic Table, and a silicon atom. 6. The method according to claim 5 , wherein the modifying group is an oxysilyl group. 7. The method according to claim 5 , wherein the monocyclic olefin ring-opening polymer has the modifying group at an end of the polymer chain thereof. 8. The method according to claim 1 , wherein the carbon black is furnace black.
