标 题 :Method for the preparation of diorganopolysiloxanes
发明人：OKAWA TADASHI

摘要:A method for the high-purity synthesis of a diorganopolysiloxane having a functional group at only one molecular chain terminal, that is characterized by the preliminary silylation with a silylating agent of the silanol group-containing impurity present in the cyclic trisiloxane, and that is characterized by preliminarily converting the silanol group-containing impurity in the cyclic trisiloxane into a lithiated material by lithiation with an organolithium compound and then silylating this lithiated material using a silylating agent that contains silicon-bonded halogen.

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.
