Patent number: 6750289Abstract: A thermoplastic elastomer produced without a hydrogenation step is functionalized utilizing a free radical initiator and a functionalizing monomer having at least one point of unsaturation. The base polymers can be produced by copolymerizing an &agr;-olefin capable of producing an amorphous backbone with a comonomer which provides a “hook” for grafting to with a living polystyrene chain. Another method is to copolymerize an &agr;-olefin monomer system capable of producing an amorphous backbone with a comonomer containing a functional group from which an anionically polymerizable monomer is grown from the backbone. A third method involves copolymerizing an &agr;-olefin monomer system capable of giving an amorphous backbone with an olefin-terminated polystyrene comonomer. In a less preferred embodiment, a conventional EPDM polymer can be metallated and a monoalkenyl aromatic compound anionically polymerizable monomer grown from the backbone.Type: GrantFiled: January 23, 2003Date of Patent: June 15, 2004Assignee: Shell Oil CompanyInventors: Bridget Ann Spence, Ronald James Hoxmeier, Robert Charles Job

Patent number: 6262145Abstract: A method for extracting and separating extractive components from fluids is provided. A first fluid and an extraction fluid are added to a vessel, thereby creating a two-phase two-layer system, wherein the first fluid and the extraction fluid are discrete and the two-phase system has a first fluid/extraction fluid interface. The two-phase system is then agitated, wherein the first fluid phase and the extraction fluid phase remain as substantially discrete layers.
