摘要:Absbpct 对位取代的二芳基鎓离子 (Arar'Ch' = 1) 与烯丙基硅烷 2,烯丙基锗烷 3 和烯丙基锡烷 4 反应的二级速率常数已在-70 至-30 oc 的 Ch2Cl2 溶液中测定.通常,Arar'Ch+ 对烯丙基元素化合物 2-4 的 Cc 双键的攻击是限速的,并导致形成 J3 元素稳定的碳鎓离子 5,随后与负抗衡离子反应得到取代产物 6 或加成产物 7.对于化合物 H2C=chch2Mph3,相对反应性为 1 (M = Si),5.6 (M = Ge) 和 1600 (M = Sn).从化合物 H2C==chch2X (X.=h,Sibu3,Snbu3) 的相对反应性,可以推导出烯丙基三烷基甲硅烷基 (5 X Ios) 和三烷基甲锡烷基 (3 X 109) 的活化作用.这种影响大大降低,当 Si 或 Sn 上的烷基被诱导性撤回取代基和烯丙基 Sicl 取代时,基团失活

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.
