摘要： A hydrogenated functionalized polymer comprises a functionalized polydiene that is selectively hydrogenated to achieve a predetermined level of saturation along at least the polydiene portion of the functionalized polydiene. The functionalized polydiene is a reaction product of 1) a living anionic elastomeric polymer initiated with a functional or nonfunctional initiator and 2) a functional polymerization terminator. In one embodiment, the living anionic elastomeric polymer is initiated with a functional initiator of formula AYLi in which Y is a divalent polymer radical; Li is a lithium atom bonded to a carbon atom of Y; and A is an amine-containing radical having the formula (X)
The functionalized polydiene is also a reaction product of a diene monomer and a polymerization terminator of formula (I):-

摘要： A process of cleaning a reactor includes providing an alcohol-containing material to the reactor; and providing a metathesis catalyst to the reactor. The reactor contains a high molecular weight polymer gel and an organoaluminum material. The alcohol-containing material is not an alkyl tartrate and may be selected from triisopropanolamine, 4-tert-butylcatechol, isopropanol, and phenol formaldehyde resins.

摘要： The compatibility between silica fillers and synthetic rubbers which are synthesized utilizing lanthanide-based catalyst systems, such as neodymium catalyst systems can be improved by terminating the polymerization with a vinyl silane terminating agent. In doing so the vinyl silane is allowed to react with the polymer chain ends of the neodymium rubber to functionalize the chain ends of the polymer chains with silicon containing groups. This results in the rubber having better characteristics for utilization in tire rubber formulations, such a tire tread formulations, that exhibit improved wear characteristics and lower rolling resistance. The process for the synthesis of such functionalized polydiene rubber comprises (1) polymerizing a diene monomer in the presence of a lanthanide-based catalyst system, and (2) terminating the polymerization with a vinyl silane terminator. The functionalized polydiene rubber composition made by this method is comprised of a polydiene rubber which is functionalized at its chain ends with a silicon containing group.
