Patent number: 6551580Abstract: A variety of phosphonylated heterochain polymers are disclosed, including, most preferably, phosphonylated polymethyl methacrylate. For each polymeric composition the phosphorous atom of a phosphorous-containing functional group is covalently bonded to a carbon atom of the polymeric chain. The phosphorous atoms are present in an amount of at least about 0.1 percent by weight in each polymeric composition.Type: GrantFiled: May 22, 2002Date of Patent: April 22, 2003Inventor: Shalaby W. Shalaby

Patent number: 6545102Abstract: Improved polymer-immobilized photosensitizer are disclosed as well as methods of preparing and using them. The polymer-immobilized photosensitizers comprise a cross-linked polymer backbone, a plurality of cationic ammonium or phosphonium groups covalently bound to the polymer backbone and an immobilized photosensitizer. The average total number of carbon atoms in the ammonium or phosphonium group is at least four and preferably at least 12. The photosensitizer can be either covalently or ionically bound to the polymer. Polymer-supported photosensitizers of the invention are unexpectedly superior in catalyzing the photosensitized oxidation of compounds containing carbon-carbon double bonds.Type: GrantFiled: September 27, 2001Date of Patent: April 8, 2003Assignee: Lumigen, Inc.Inventors: Hashem Akhavan-Tafti, Richard S. Handley, Mark D. Sandison, Randall K. Larkin

Patent number: 6528603Abstract: The present invention provides novel organic copolymers comprising alternating functional groups, wherein one functional group is phosphonate. In one embodiment, the copolymers comprise alternating phosphonate and N-substituted succinimide functional groups. In another embodiment, the copolymers are synthesized from maleimide and vinyl ether monomers, wherein the vinyl ether monomer possesses a pendant phosphonate functionality and the maleimide monomer is an N-substituted maleimide. Methods of synthesizing thin films with the novel organic copolymers, as well as chemical precipitation methods using the novel organic copolymers, are also provided.Type: GrantFiled: January 13, 2000Date of Patent: March 4, 2003Assignee: Board of Trustees operating Michigan State UniversityInventors: Gary J. Blanchard, Punit Kohli
