专利号:US-11767388-B1 优先权日:2019-09-18 标 题 :Silicon-functionalized rubber 发明人:ENSIGN SETH CODY; VIELHABER MARGARET FLOOK; JOHNGRASS JENA LYNN; MA LIQING 权利人:GOODYEAR TIRE & RUBBER 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.

专利号:US-7776250-B2 优先权日:2004-09-15 标 题:Imprinted polymer support 发明人:LOW HONG YEE; PARAPPUVEETIL SARANGADHARAN SURESH; KONG YEN PENG; DARMONO KARAN 权利人:AGENCY SCIENCE TECH & RES 摘要:There is disclosed an imprinted polymer support for solid phase organic synthesis (SPOS). The polymer support being obtainable from a method that comprises providing a substrate and a mold, the mold having a defined surface pattern. A composition is placed between the defined surface pattern of the mold and the substrate. The composition comprises a polymerisation medium with at least one functional monomer and a free radical initiator. The composition is polymerised to form an array of polymer imprints adhered to the substrate.
