摘要:Acyclic diene metathesis (ADMET) has been utilized in the synthesis of carbosilane and carbosiloxane polymers bearing a latent reactive methoxy-functional group on each repeat unit. The polymerization results in a linear thermoplastic polymer. The latent reactive methoxy groups remain inert during polymerization; however, exposure to moisture triggers hydrolysis and the formation of a chemically cross-linked thermoset. The thermoset's properties can be modified by varying the ratio of carbosilane and carbosiloxane repeat units in the final material. Also, increasing cross-link density by using cross-linkable chain-end groups and increasing the run length of the soft phase, maximizing phase separation and elasticity, allows for the synthesis of elastic thermosets exhibiting good tensile strength. Adding a trifunctional ADMET active chain-end cross-linker to the system improved the mechanical behavior of the resulting polymer.

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:To provide a material suitable for a nonaqueous electrolyte battery having high-temperature durability. An ionic complex of the present invention is represented by any of the following formulae (1) to (3). For example, in the formula (1), A is a metal ion, a proton, or an onium ion; M is any of groups 13 to 15 elements. R 1 represents a C 1 to C 10 hydrocarbon group which may have a ring, a heteroatom, or a halogen atom, or —N(R 2 )—. R 2 at this time represents hydrogen atom, alkali metal atom, a C 1 to C 10 hydrocarbon group which may have a ring, a heteroatom, or a halogen atom. R 2 can also have a branched chain or a ring structure when the number of carbon atoms is 3 or more. Y is carbon atom or sulfur atom. a, o, n, p, q, and r are each predetermined integers.
