The zwitterionic group is usually an ammonium phosphate ester, preferably a choline, zwitterionic group and the polymer containing it may be produced by the free radical polymerization of ethylenically unsaturated monomers including a monomer bearing the zwitterionic group. Blending of the two polymers may be achieved by dry blending particulate polymers or by mixing the polymers in liquid dispersion or solution followed by removal of the liquid medium. The fibrinogen absorption and/or platelet activation of polymers may be reduced to a value of less than 80% or even less than 60% of the base polymer by introducing amounts of more than 10% or more than 30% of the zwitterionic group containing polymer.Type: GrantFiled: January 26, 1998Date of Patent: November 21, 2000Assignee: Biocompatibles LimitedInventors: Stephen Alister Jones, Peter William Stratford, Steven Rimmer

Patent number: 6100337Abstract: 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 .alpha.-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 .alpha.-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 .alpha.-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: May 18, 1998Date of Patent: August 8, 2000Assignee: Shell Oil CompanyInventors: Bridget Ann Spence, Ronald James Hoxmeier, Robert Charles Job
