20080312351 | Tetraalkylammonium Carboxylate Salts as Trimerization Catalysts for Spray Foam Applications - The present invention provides a method to produce a polyisocyanurate/-polyurethane spray foam using a trimerization catalyst composition having tetraalkylammonium salt of a sterically hindered carboxylic acid or an α,β-unsaturated carboxylic acid. | 12-18-2008 |
20100222443 | BLOWING AGENT COMPOSITION - A subject-matter of the present invention is a blowing agent composition comprising an organic solvent with a boiling point, at atmospheric pressure, of greater than 0° C. and having a low GWP and at least one compound (C) chosen from haloketones, fluoroacids, fluoroesters, fluoroamines, (hydro)fluoroethers, (hydro) fluorothioethers, (hydro)fluoroolefins, cyclic (hydro)fluorocarbons and iodofluoro(hydro)carbons. | 09-02-2010 |
20110124753 | Rigid Polyurethane Foam Having Excellent Insulating Properties and Method for Preparing the Same - The present invention provides rigid polyurethane foam comprising thermally expandable particles which are displaced to penetrate a strut of a structure of the polyurethane foam so that the particles are exposed into one or more cells of the polyurethane foam during foaming. Further, the rigid polyurethane foam can comprise hollow thermally expanded particles which are displaced to penetrate a surface of a cell in the polyurethane foam so that the particles are exposed into one or more cells of the polyurethane foam during foaming. The rigid polyurethane of the present invention can have excellent insulating properties. | 05-26-2011 |
20120035288 | FORMING COPOLYMER FROM BICONTINUOUS MICROEMULSION COMPRISING MONOMERS OF DIFFERENT HYDROPHILICITY - A copolymer defines interconnected pores and comprises polymerized monomers. The monomers comprise a first monomer more hydrophilic than 2-hydroxyethyl methacrylate (HEMA), and a second monomer as hydrophilic as, or less hydrophilic than, HEMA. In a method of forming a polymer, a bicontinuous microemulsion comprising water, a surfactant, and a combination of monomers copolymerizable for forming a porous copolymer is provided. The combination of monomers comprises the first and second monomers. The monomers in the bicontinuous microemulsion are polymerized to form the porous copolymer. The first monomer may comprise N-vinylpyrrolidone (NVP) or methacrylic acid (MAA). The second monomer may comprise HEMA or methyl methacrylate (MMA). | 02-09-2012 |
