Patent number: 7825199Abstract: Further improvements have been made in processes for controlled polymerization of free radically (co)polymerizable monomers mediated by a transition metal complex participating in a redox reaction which involves transfer of a radically transferable atom or group to and from an initiator or dormant polymer and the growing active polymer chain ends. Two improvements involve the choice of counterion in the transition metal complex. In one improvement the transition metal is held in close conjunction with a solid support through interaction with a counterion directly attached to the support. This cognition also allows for improvements in catalyst utilization including catalyst recovery and recycle. In another improvement, particularly suitable for controlled polymerization of certain monomers with an expanded range of transition metals, the function of counterion and ligand in the development of the transition metal based catalyst is superseded by use of salt containing a soluble organic counterion.Type: GrantFiled: March 23, 2000Date of Patent: November 2, 2010Assignee: Carnegie Mellon UniversityInventors: Krzysztof Matyjaszewski, Scott G.

Patent number: 6953829Abstract: A catalyst system comprising at least one metallocene, at least one cocatalyst, at least one support material and, if desired, further organometallic compounds is described. The catalyst system can advantageously be used for the polymerization of olefins and displays a high catalyst activity and gives a good polymer morphology without it being necessary to use aluminoxanes such as methylaluminoxane (MAO), which usually has to be used in high excess, as cocatalyst.Type: GrantFiled: December 13, 2000Date of Patent: October 11, 2005Assignee: Basell Polyolefine GmbHInventors: Roland Kratzer, Cornelia Fritze, Jörg Schottek

Patent number: 6951831Abstract: A catalyst composition for use in dimerizing, co-dimerizing or oligomerizing olefins comprises: at least one zero-valent nickel complex; at least one acid with formula H+X? in which X? represents an anion; and at least one ionic liquid with general formula Q+ A? in which A? is an anion identical to or different from X?. The composition can also comprise a nitrogen-containing ligand. It can be used in dimerizing, co-dimerizing, oligomerizing and in polymerizing olefins.Type: GrantFiled: February 3, 2003Date of Patent: October 4, 2005Assignee: Institut Francais du PetroleInventors: Vincent Lecocq, Hélène Olivier-Bourbigou

Patent number: 6908970Abstract: A process for producing a hydrogenated product of a polymer prepared through ring-opening polymerization which comprises a polymerization step of polymerizing a cyclic olefin through ring-opening polymerization in the presence of a polymerization catalyst comprising an organoruthenium compound or an organoosmium compound to prepare a polymer, and a hydrogenation step of adding a hydrogenation catalyst and hydrogen into a polymerization system resulting from the polymerization step to hydrogenate the carbon-carbon double bonds of the polymer prepared through the ring-opening polymerization. When the organoruthenium compound- or organoosmium compound-containing catalyst further comprises a carbene compound, the catalyst exhibits a higher activity for the ring-opening polymerization.Type: GrantFiled: October 7, 2002Date of Patent: June 21, 2005Assignee: Zeon CorporationInventors: Yasuo Tsunogae, Masato Sakamoto, Masaharu Tokoro, Kazunori Taguchi
