Patent number: 9290462Abstract: This invention relates to the composition of matter of polythiols having a chemical structure in FIG. 1. In certain embodiments this invention provides a polythiol with low or no odor and which is a liquid, a waxy solid or a semi-solid at 22° C. In another embodiment the polythiols have a viscosity lower than 100,000 cP at 50° C. In other embodiments, the invention provides a mixture of thiol compounds or a mixture of thiol and amine compounds.Type: GrantFiled: December 17, 2014Date of Patent: March 22, 2016Assignee: TDA Research, Inc.Inventor: Silvia DeVito Luebben

Patent number: 9040635Abstract: A polymer, optionally made from renewable sources, comprising a specific chemical structure that is a result of the polymerization of ?-hydroxycarbonyl compounds (alpha-hydroxycarbonyl compounds), particularly ?-hydroxyaldehydes (alpha-hydroxyaldehydes) and ?-hydroxyketones (alpha-hydroxyketones), or glycolaldehyde. A method of polymerization, the method comprising the step of reacting trimethylsilyl trifluoromethanesulfonate with the cyclic dimer of one or more ?-hydroxycarbonyl compounds. A method of making said polymer, the method comprising dehydrating a cyclic dimer of one or more ?-hydroxycarbonyl compounds. An end-capped polymer made from one or more ?-hydroxycarbonyl compounds and terminal end-cap groups.Type: GrantFiled: January 17, 2014Date of Patent: May 26, 2015Assignee: TDA Research, Inc.Inventors: Silvia DeVito Luebben, James William Raebiger, Aaron Jeremy Skaggs

Patent number: 8097348Abstract: Pi-conjugated organoboron polymers for use in thin-film organic polymer electronic devices. The polymers contain aromatic and or unsaturated repeat units and boron atoms. Pi-conjugated organoboron polymers which are end capped, derivatized with solubilizing groups or both exhibit improved solubility and handling properties beneficial for the formation of thin films useful for device fabrication. The vacant p-orbital of the boron atoms conjugate with the pi-conjugated orbital system of the aromatic or unsaturated monomer units extending the pi-conjugation length of the polymer across the boron atoms. The pi-conjugated organoboron polymers are electron-deficient and, therefore, exhibit n-type semiconducting properties, photoluminescence, and electroluminescence.Type: GrantFiled: March 19, 2007Date of Patent: January 17, 2012Assignee: TDA Research, Inc.Inventors: Silvia DeVito Luebben, Shawn Sapp

Patent number: 7279534Abstract: The present invention provides block copolymers containing at least one block of a poly(heteroaromatic) polymer and at least two blocks of a non-conjugated polymer. The chemically different blocks of the copolymer are covalently bonded to each other in an alternating fashion through an appropriate linkage group. The poly(heteroaromatic) block may exist in its neutral or oxidized form, and when in the oxidized form, it associates with organic or inorganic counter-anions to balance the charge. The poly(heteroaromatic) polymer is an intrinsically conducting polymer (ICP), and when in the oxidized form it is electrically conducting. When the ICP block or blocks of the block copolymer are in the doped form, the block copolymer is electrically conducting. Preferably the conducting block copolymers have conductivities in the range 10?6-103 S/cm. Block copolymers of this invention are soluble or dispersible in water, one or more organic solvents, or in a mixture thereof at a level of at least about 0.1 g/liter.Type: GrantFiled: September 3, 2002Date of Patent: October 9, 2007Assignee: TDA Research, Inc.Inventors: Silvia DeVito Luebben, Brian Elliott, Carolina Wilson

Patent number: 7244498Abstract: Surface-modified nanoparticles of boehmite, and methods for preparing the same. Aluminum oxyhydroxide nanoparticles are surface modified by reaction with selected amounts of organic acids. In particular, the nanoparticle surface is modified by reactions with two or more different carboxylic acids, at least one of which is an organic carboxylic acid. The product is a surface modified boehmite nanoparticle that has an inorganic aluminum oxyhydroxide core, or part aluminum oxyhydroxide core and a surface-bonded organic shell. Organic carboxylic acids of this invention contain at least one carboxylic acid group and one carbon-hydrogen bond. One embodiment of this invention provides boehmite nanoparticles that have been surface modified with two or more acids one of which additional carries at least one reactive functional group.Type: GrantFiled: May 3, 2005Date of Patent: July 17, 2007Assignee: TDA Research, Inc.Inventors: Ronald Lee Cook, Silvia DeVito Luebben, Andrew William Myers, Bryan Matthew Smith, Brian John Elliott, Cory Kreutzer, Carolina Wilson, Manfred Meiser

Patent number: 6986943Abstract: The present invention relates to a new class of surface modified particles and to a multi-step surface modification process for the preparation of the same. The multi-step surface functionalization process involves two or more reactions to produce particles that are compatible with various host systems and/or to provide the particles with particular chemical reactivities. The initial step comprises the attachment of a small organic compound to the surface of the inorganic particle. The subsequent steps attach additional compounds to the previously attached organic compounds through organic linking groups.Type: GrantFiled: June 12, 2002Date of Patent: January 17, 2006Assignee: TDA Research, Inc.Inventors: Ronald Lee Cook, Brian John Elliott, Silvia DeVito Luebben, Andrew William Myers, Bryan Matthew Smith

Patent number: 6887517Abstract: A new class of surface modified particles and a multi-step Michael-type addition surface modification process for the preparation of the same is provided. The multi-step Michael-type addition surface modification process involves two or more reactions to compatibilize particles with various host systems and/or to provide the particles with particular chemical reactivities. The initial step comprises the attachment of a small organic compound to the surface of the inorganic particle. The subsequent steps attach additional compounds to the previously attached organic compounds through reactive organic linking groups. Specifically, these reactive groups are activated carbon—carbon pi bonds and carbon and non-carbon nucleophiles that react via Michael or Michael-type additions.Type: GrantFiled: June 12, 2002Date of Patent: May 3, 2005Assignee: TDA ResearchInventors: Ronald Lee Cook, Brian John Elliott, Silvia DeVito Luebben, Andrew William Myers, Bryan Matthew Smith
