Tire with rubber component comprised of a composite of rubber and film of syndiotactic polybutadiene integral with its surface |
摘要 |
This invention relates to a tire having at least one rubber component which contains a cast, extruded, or calendered film of syndiotactic polybutadiene polymer. The syndiotactic polybutadiene polymer film is integral with the surface of the rubber component in a sense of being co-cured therewith. Such film may be added directly to the tire during the building process or involve a separate process of producing a tire component as a composite of the film and a rubber composition (rubber component) prior to the tire building stage. Such composite can be as is or partially pre-cured before being applied in the tire building process. The syndiotactic polybutadiene polymer film is provided to promote both stability and age durability for the tire component.
