Patent number: 8604091Abstract: One- and two-part spray non-isocyanate foams that include an amide-based oligomer containing pendant carboxylic acid and a polyfunctional aziridine crosslinking agent is provided. The amide oligomer typically contains urea links, urethane links or both groups. Additionally, the foams may include one or more plasticizer, a non-functionalized resin, a surfactant, and/or a thickening agent or rheology modifier. The amide oligomer does not contain any isocyanate groups, and, as a result, there are no free isocyanate moieties generated during formation of the foam that may be potentially hazardous to workers installing the foam. The presence of the urethane segments on the oligomer permits for the generation of a polyurethane foam without the drawbacks of conventional polyurethane foams. The foams may be used to fill cavities, cracks, gaps and crevices, such as around windows and doors, and may also be used in flash and batt systems.Type: GrantFiled: August 30, 2011Date of Patent: December 10, 2013Assignee: Owens Corning Intellectual Capital, LLCInventor: Fatemeh Nassreen Olang

Patent number: 8569391Abstract: The invention provides mesostructured materials and methods of preparing mesostructured materials including metal-rich mesostructured nanoparticle-block copolymer hybrids, porous metal-nonmetal nanocomposite mesostructures, and ordered metal mesostructures with uniform pores. The nanoparticles can be metal, metal alloy, metal mixture, intermetallic, metal-carbon, metal-ceramic, semiconductor-carbon, semiconductor-ceramic, insulator-carbon or insulator-ceramic nanoparticles, or combinations thereof. A block copolymer/ligand-stabilized nanoparticle solution is cast, resulting in the formation of a metal-rich (or semiconductor-rich or insulator-rich) mesostructured nanoparticle-block copolymer hybrid. The hybrid is heated to an elevated temperature, resulting in the formation of an ordered porous nanocomposite mesostructure. A nonmetal component (e.g., carbon or ceramic) is then removed to produce an ordered mesostructure with ordered and large uniform pores.Type: GrantFiled: January 13, 2009Date of Patent: October 29, 2013Assignee: Cornell UniversityInventors: Scott Warren, Ulrich Wiesner, Francis J.
