权利人:ARAMCO SERVICES CO; SAUDI ARABIAN OIL CO
摘要:A composition of matter including a mono-facial polymer-grafted graphene particle and an aqueous-based drilling fluid is provided. In the composition, a first side of the graphene particle has a grafted polymer. A method of lubricating a tool surface using the composition of matter is also provided. The method includes providing an aqueous-based drilling fluid, the aqueous-based drilling fluid having a mono-facial polymer-grafted graphene particle, and introducing the aqueous-based drilling fluid into a wellbore such that it contacts a tool surface to form a coated tool. A drilling tool having a mono-facial polymer-grafted graphene particle adhered to its surface is also provided.

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:The present invention relates to the production of amphiphilic copolymer networks, or co-networks, and to methods for preparing amphiphilic co-networks. Furthermore, the present invention relates to products and/or films made from the amphiphilic co-networks produced in accordance with the synthesis methods of the present invention. Additionally, the present invention relates to crosslinked amphiphilic co-networks comprising at least one hydrophilic segment and at least one hydrophobic segment. In one embodiment, the hydrophilic segments include at least one polyalkyl glycol (e.g., polyethylene glycol (PEG)) and the hydrophobic segments include at least one di-alkenyl and/or di-alkynyl terminated polysiloxane (e.g., polydimethylsiloxane (PDMS)). In another embodiment, the amphiphilic co-networks of the present invention are optically clear and highly oxophilic.
