  • Publication number: 20220081367
    Abstract: Thermoset ceramic compositions and a method of preparation of such compositions. The compositions are advanced organic/inorganic hybrid composite polymer ceramic alloys. The material combines strength, hardness and high temperature performance of technical ceramics with the strength, ductility, thermal shock resistance, density, and easy processing of the polymer. Consisting of a branched backbone of silicon, and alumina, with highly coordinated Si—O—Si or Al—O—Al bonds, the material undergoes sintering at 7 to 300 centigrade for 2 to 94 hours from water at a pH between 0 to 14, humidity of 0 to 100%, with or without vaporous solvents.

  • Patent number: 9200177
    Abstract: The instant invention provides a high-solid, solvent-free alkyd dispersion, and a continuous process for producing the same. The aqueous alkyd dispersion, according to the present invention comprises (a) from 40 to 70 percent by weight of one or more alkyds based on the total weight of the dispersion, wherein each one or more alkyds has an acid value of less than 20 and a molecular weight (Mn) in the range of greater than 1000 Dalton; (b) from less than 10 percent by weight of one or more surfactants, based on the total weight of the dispersion; and (c) from 30 to 55 percent by weight of water, based on the total weight of the dispersion; and the dispersion has an average particle size diameter in the range of 0.05 to 5 ?m.

  • Patent number: 9169367
    Abstract: The present invention appreciates that compounds comprising nitrogen-containing moieties that are at least divalent (e.g., urea, urethane, amide, etc.) can be reacted with azides using at least radiation energy to initiate the reaction between at least a portion of the compounds and the azides to form membranes that have surprisingly high selectivities for acid gases relative to nonpolar gases such as hydrocarbons. The membranes are also resistant to CO2 plasticization and have high acid gas flux characteristics. The resultant membranes can be extremely thin (e.g., 10 micrometers or less), which promotes high permeability for the acid gas and can translate into high productivity on a scaled-up, industrial level.

  • Publication number: 20140221561
    Abstract: An alkyd surfactant which is effective in emulsifying alkyd resins is formed by copolymerization of at least one monomer having a hydrophilic group, at least one ethylenically unsaturated fatty acid or ester, and optionally, at least one polyol, and has a low degree of branching. Stable alkyd emulsions are formed by emulsification of alkyd resins with the alkyd surfactant. Since the alkyd surfactant has ethylenically unsaturated hydrophobe groups which can react with the alkyd resin during curing, the alkyd surfactant is not subject to migration, blooming or leaching from cured coatings.
