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.

摘要:Hyperbranched polycarbosilanes, polycarbosiloxanes, polycarbosilazenes and copolymers thereof are prepared by reacting a difunctional or polyfunctional monomer having functional groups of one type (A) without any other functional groups capable of reacting significantly during polymerization, and a difunctional or polyfunctional monomer having functional groups of another type (B) without any other functional groups capable of reacting significantly during polymerization, wherein each A-functional group is reacted with a B-functional group, and wherein at least one of the monomers has a functionality of at least three. The process enables hyperbranched polycarbosilanes, polycarbosiloxanes, polycarbosilazenes and copolymers thereof to be prepared at a lower cost than with conventional synthesis processes, and provides greater flexibility in the preparation of a larger variety of different types of hyperbranched polycarbosilanes, polycarbosiloxanes, polycarbosilazenes and copolymers thereof.
