摘要:Chiral Ansa-Zirconocene Complexes With A Trimethylene Link Between The Si Bridge Atom And An Alpha-Position Of Each C-5 Ring Ligand Were Prepared; Two Representatives,With I-Propyl And T-Butyl Groups As Beta-Substituents,Were Structurally Characterized,The Properties Of These Complexes With Respect To Mao-Activated Propene Polymerization Were Studied In Comparison With Those Of Their Me(2)Si-Bridged Analogs. The T-Butyl-Substituted Spirosilane Complex Gives A Polymer With Relatively High Content Of 3,1-Insertions. These Increased Regioirregularities Appear To Be Associated With Decreased Coordination Gap Aperture And Increased Lateral Extension Angles Of The Spirosilane-Bridged Zirconocene Complexes; This Notion Is Supported By A Molecular-Mechanics Analysis Of Alternative Olefin-Insertion Transition States.

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.
