摘要:已经制备了同时与硅连接的同时含有氯和二甲基氨基的几种新化合物.一般的方法包括使合适的聚氯硅烷在乙醚中的溶液在约200oc下反应.-用二甲胺的乙醚溶液冷却50°.以这种方式制备的是ch 3 Si(nme 2)cl 2,Ch 3 Si(nme 2)2-Cl,Phsi(nme 2)cl 2,Phsi(nme 2)2 Cl,Ch 3(h)si(nme 2)氯,(ch 3)2的si(nme 2)氯,Ch 2 ch(ch3)si(nme 2)cl和ph 2 Si(nme 2)cl.这些化合物的光谱与全卤和全胺系列光谱的比较表明,用nme 2代替cl导致与硅连接的其他基团的共振发生高场移位,该移位与在取代ch 3时观测到的平行对于cl.红外光谱中的ν(sih)和NMR光谱中的δ(sih)呈线性关系.

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.
