  • Patent number: 9470666
    Abstract: Disclosed is a pinhole inspection apparatus, system and method for a membrane electrode assembly of a fuel cell, which can easily detect the position of a pinhole using water and a pH test paper from discoloration caused when the water is in contact with the pH test paper through the pinhole, thus solving the existing problems and allowing the membrane electrode assembly to be reused after the inspection. In particular, a lower fixture is configured to support the membrane electrode assembly and water is uniformly distributed on an upper surface of the membrane electrode assembly. A pH test paper is inserted between the membrane electrode assembly and the lower fixture and discolored upon coming in contact with water that passes through a pinhole in the membrane electrode assembly, thus detecting the presence and position of the pinhole.

  • Patent number: 8802801
    Abstract: A self-healing polymer additive includes diene (e.g. butadiene, cyclohexadiene, pentadiene, tetrahydrofuron or their derivatives) and dienophile (e.g. maleic anhydride, maleamide, conjugated carbonyls or their derivatives etc.). One polymer includes tetrahydrofuron and maleimide. Furfurylamine 12 (1-10 gm) is diluted in acetone. Under an inert atmosphere an equivalent amount of granular maleic acid is added slowly, and the reaction is allowed to take place. Resulting maleamic acid precipitates. The maleamic acid product is separated, dried and purified by re-crystallization. The maleamic (1-5 gm) acid is dissolved in acetic anhydride along with a catalytic amount of sodium acetate. The resulting solution is heated for a few hours in 80-120° C. The precipitated final product is separated, purified and dried in a vacuum.

  • Patent number: 8470946
    Abstract: Carbon nanotube (CNT) yarns and sheets having enhanced mechanical strength using infused and bonded nano-resins. A CNT yarn or sheet is surface-activated to produce open bonds in the CNT walls prior to resin infusion. The CNT yarn or sheet is infused with a low viscosity nano-resin that penetrates spaces between individual CNTs and is cured to cross-link and chemically bond to the CNT walls, either directly or through a functional molecule, to bond the individual CNTs or ropes to each other. The nano-resin can comprise dicyclopentadiene having an uncured viscosity near that of water. The cross-linking process involves ring-opening metathesis polymerization and catalysis of the nano-resin in combination with a functionalizing material such as norbornene, to enhance bonding between the carbon and nano-resin. The process increases load capability, tensile strength, and elastic modulus of the yarns and sheets, for use as a structural component in composite materials.

  • Patent number: 6803429
    Abstract: A catalytic method is provided for a ring-opening cross-metathesis reaction between a cycloolefinic substrate and a second olefinic reactant, wherein the catalyst used is a transition metal alkylidene complex substituted with an N-heterocyclic carbene ligand. The substrates are selected so that the rate of the cross-metathesis reaction of the second olefinic reactant, kCM, is greater than or equal to the rate of the ring-opening metathesis reaction, kRO. In this way, the predominant ROCM product is a monomer, dimer, and/or oligomer, but not a polymer. The invention additionally provides for selective production of an end-differentiated olefinic product, using trisubstituted cycloolefins as substrates and/or a subsequent cross-metathesis reaction following an initial ROCM step. The cycloolefinic substrates include low-strain olefins such as cyclohexene as well as higher strain olefins such as cyclooctene.

  • Patent number: 6627720
    Abstract: A method is provided for producing hyperbranched polymers comprising heating a polymerizable reaction charge comprising (a) a monomer mixture comprising 50-99.1% by weight of at least one monoethylenically unsaturated monomer and 0.1-50% by weight of one or more multiethylenically unsaturated monomers and (b) if at least one ethylenically unsaturated monomer of the monomer mixture is not a thermally initiating monomer, a free radical polymerization initiator, to a temperature in the range from about 250° C. to about 400° C. in a continuous reactor which allows mixing of the reactor contents for a residence time of from about 2 minutes to about 60 minutes, provided that if the total amount of multiethylenically unsaturated monomer is less than 3% by weight of the monomer mixture than at least one of said one or more multiethylenically unsaturated monomers must be tri- or greater ethylenically unsaturated.

  • Patent number: 6624265
    Abstract: The invention discloses ruthenium alkylidene complexes of the type (PCy3)(L)Cl2Ru(CHPh), where L is a triazolylidene ligand of the general formula: These catalysts have been found to be considerably more active for olefin metathesis at elevated temperatures than the parent catalyst (PCy3)2Cl2Ru(CHPh)(2). For example, complex 14 (L=1,3,4-triphenyl-4.5-dihydro-1H-triazol-5-ylidene) is able to catalyze the ring-closing metathesis of substituted dienes to give tetra-substituted cyclic olefins in good yield. In addition, this complex demonstrates the analogous stability towards oxygen and moisture exhibited by ruthenium alkylidene 2.

  • Patent number: 6391997
    Abstract: A process for production of diene rubber polymers wherein, during production of a diene rubber polymer by emulsion polymerization, the polymerization is initiated using a portion of the starting material and the polymerization is continued with either continuous or intermittent dropwise addition of the remainder of the starting material during the polymerization, and wherein at least ½ of the total amount of the water and of the monomer in the starting material used is added dropwise during the polymerization, and the temperature of the dropwise added water and monomer is kept to at least 20° C. below the polymerization temperature. The process can produce industrially useful diene rubber polymer latexes at a high productivity rate.

  • Patent number: 6310151
    Abstract: Conjugated diolefins, optionally in combination with other unsaturated compounds which may be copolymerized with the diolefins, are polymerized by performing the polymerization of the diolefins in the presence of catalysts based on cobalt compounds, organoaluminum compounds and modifiers in the presence of aromatic vinyl compounds at temperatures of −30° C. to +80° C. By means of the process according to the invention, it is possible straightforwardly to produce solutions of polydiolefins, such as polybutadiene, having different 1,2 unit contents in aromatic vinyl compounds, which solutions may then, for example, be further processed to yield ABS or HIPS.

  • Patent number: 6281309
    Abstract: Fluorinated solid acids and supported fluorinated solid acids are used as catalysts for the polymerization of a feed stream containing at least one of pure monomer, C5 monomers, and C9 monomers to produce hydrocarbon resins. Freely-associated water may be removed from the fluorinated solid acid catalyst and/or supported fluorinated solid acid catalyst prior to use. Resins with softening points (Ring and Ball) in the range of about 5° C. to 170° C. can be prepared. These catalysts offer advantages over the traditional Friedel-Crafts polymerization catalysts since the acid sites are an integral part of the solid. The fluorinated solid acid catalysts and supported fluorinated solid acid catalysts are relatively nonhazardous, reusable catalysts which eliminate or at least reduce contamination of the resulting resin products with acid residues or by-products.
