Patent number: 7501461Abstract: One aspect of the current invention is a halogen containing epoxy composition and a method of producing the same. A functional halogen group, fluorine in one case, is incorporated into an epoxy coating by using a functionalized amine curing agent in small amounts. Functionalized amine curing agents are cheaper and easier to produce from small amine precursors when compared to the cost and complexity of functionalizing bulky epoxy resins. Amine curing agents are incorporated into a cured epoxy network. However, many functional groups will affect the reactivity of the curing reaction due to electronegativity effects. By using small amounts of functionalized amines with a large amount of non-functionalized agent, the effect is small and in the case of migration, it can be advantageous for tribological, mechanical and other properties of epoxies and epoxy-containing materials.Type: GrantFiled: April 12, 2005Date of Patent: March 10, 2009Assignee: University of North TexasInventors: Bryan Bilyeu, Witold Brostow, Kevin Menard

Patent number: 6969752Abstract: The present invention is an adhesive or coating composition that is dispersible or dissolvable in water, making it useful in as a coating or adhesive in paper intended for recycling. The composition of the present invention is cationically charged thereby binding with the fibers of the paper slurry and thus, resulting in reduced deposition of adhesives on equipment during the recycling process. The presence of the composition of the present invention results in stronger interfiber bonding in products produced from the recycled fibers.Type: GrantFiled: July 21, 2000Date of Patent: November 29, 2005Assignee: Georgia Tech Research CorporationInventors: Yulin Deng, Zegui Yan

Patent number: 6951902Abstract: A polymeric composition that generates nitric oxide and a process for rendering the surface of a substrate nonthrombogenic by applying a coating of the polymeric composition to the substrate are disclosed. The composition comprises: (1) a crosslinked chemical combination of (i) a polymer having amino group-containing side chains along a backbone forming the polymer, and (ii) a crosslinking agent containing functional groups capable of reacting with the amino groups; and (2) a plurality of nitric oxide generating functional groups associated with the crosslinked chemical combination. Once exposed to a physiological environment, the coating generates nitric oxide thereby inhibiting platelet aggregation. In one embodiment, the nitric oxide generating functional groups are provided by a nitrated compound (e.g., nitrocellulose) imbedded in the polymeric composition. In another embodiment, the nitric oxide generating functional groups comprise N2O2? groups covalently bonded to amino groups on the polymer.Type: GrantFiled: August 16, 2002Date of Patent: October 4, 2005Assignee: Michigan Biotechnology InstituteInventors: William F. McDonald, Amy B. Koren

Patent number: 6881820Abstract: This invention is a series of rod-coil block polyimide copolymers that are easy to fabricate into mechanically resilient films with acceptable ionic or protonic conductivity at a variety of temperatures. The copolymers consist of short-rigid polyimide rod segments alternating with polyether coil segments. The rods and coil segments can be linear, branched or mixtures of linear and branched segments. The highly incompatible rods and coil segments phase separate, providing nanoscale channels for ion conduction. The polyimide segments provide dimensional and mechanical stability and can be functionalized in a number of ways to provide specialized functions for a given application. These rod-coil black polyimide copolymers are particularly useful in the preparation of ion conductive membranes for use in the manufacture of fuel cells and lithium based polymer batteries.Type: GrantFiled: May 13, 2002Date of Patent: April 19, 2005Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Mary Ann B.
