Patent number: 6235849Abstract: The invention is directed to polymers containing a repeating unit derived from a norbornene sulfonamide. These may be addition polymers which include copolymers with one or more comonomers such as norbornene, ethylene, an acrylate or sulfur dioxide or carbon monoxide. Said monomers may be polymerized using single or multicomponent Group VIII catalysts. The norbornene sulfonamides can also form ROMP polymers using known metathesis catalysts. Preferably the ROMP polymers may be hydrogenated to give more stable polymers.Type: GrantFiled: February 3, 2000Date of Patent: May 22, 2001Assignee: The B. F. Goodrich CompanyInventors: Saikumar Jayaraman, Richard Vicari, Larry F. Rhodes

Patent number: 6193909Abstract: Cross-linked electrically conductive polymers, in particular electrically conductive, polyaniline are described. Dopants and substituents having pendant cross-linkable functionality are used which form a cross-linked conducting polymer network. The cross-linking functionality can be hydrogen-bonding as well as chemically polymerizable or cross-linkable. A conjugated path between chains can also be incorporated. The resulting cross-linked conducting polymers have enhanced thermal and environmental stability. The dopant cannot readily be washed out with solvents or diffuse out upon exposure to heat. In addition, the cross-linked polymers have enhanced electrical conductivity.Type: GrantFiled: February 2, 1996Date of Patent: February 27, 2001Assignee: International Business Machines CorporationInventors: Marie Angelopoulos, Jeffrey D. Gelorme, Yun Hsin Liao, Jane M. Shaw

Patent number: 6184302Abstract: The present invention relates to water-insoluble cationized solids obtained by treating solids with cationic homopolymers and/or copolymers comprising allylic and/or vinylic double bonds, where cationization is carried out using nitrogen-containing cationic polymers and/or copolymers which comprise from 0.5 to 100 mol-%, preferably from 5 to 20 mol-%, of said double bonds, based on nitrogen equivalents. The invention relates in particular to cationized solids obtained by cationization with allylated and/or vinylated derivatives of amino-containing polymers and/or copolymers. The invention also embraces the preparation of cationized solids by free-radical crosslinking of the abovementioned cationic polymers and/or copolymers in the presence of solids. The products obtained are in general at least 95% insoluble in water. They are obtained by cationizing mineral materials and, preferably, cellulose and are used preferably as retention aids and/or fixing agents in papermaking.Type: GrantFiled: May 11, 1998Date of Patent: February 6, 2001Assignee: Clariant CorporationInventor: Oliver Eyrisch
