Heterocyclic Reactant Contains 1,2-epoxy Group Patents (Class 525/208)
  • Patent number: 7084211
    Abstract: A cold setting coating composition comprises an urethane-modified vinyl resin (A) produced by reacting a reaction product with an isocyanate group-possessing compound (c). The reaction product is produced by reacting an epoxy group-containing vinyl copolymer (a) with a fatty acid component (b) containing an unsaturated fatty acid. The vinyl copolymer (a) is a copolymer of a first polymerizable unsaturated monomer containing an epoxy group and a second polymerizable unsaturated monomer. The composition also comprises a polymer dispersion (B) obtained by polymerizing two or more of vinyl monomers in the presence of a dispersion stabilizer (d) in an organic liquid in which vinyl monomers are soluble and a polymer formed from the monomers is insoluble. The dispersion stabilizer (d) is soluble in the organic liquid. The coating composition improved weathering resistance and water resistance of the resulting coated film.

  • Patent number: 7041740
    Abstract: Heat-settable epoxy resin mixtures are provided that can be used alone or in combination with fibers to form large composite material structures without the need for high consolidation pressures. The heat-settable resin mixture is composed of a resin component, curing agent component and a particulate component. The particulate component includes rigid-rod polymer particles that dissolve when the heat-settable resin is heated to temperatures within a predetermined processing window. After heating to the processing temperature, the resulting heat-set resin is cooled to form a curable solid resin. The curable solid resin may be stored indefinitely or re-heated to curing temperatures to form a cured product.

  • Patent number: 6492462
    Abstract: The rheological properties of a crosslinkable resin system are modified by the presence of a side chain crystalline (SCC) polymer (or a similar crystalline polymer which melts over a narrow temperature range). The polymer dissolves in the curable system at temperatures above the melting point of the crystalline polymer (Tp), but when the system is then cooled to a temperature below Tp, at least partially forms a separate phase in the curable system. Below Tp, this separate phase substantially increases the viscosity of the curable system (i.e. makes it thicker than the same system without the crystalline polymer). This is particularly valuable for sheet molding composites (SMCs) in which the increase in viscosity makes the composites less tacky, and for dry film resists (DFRs). Above Tp, the curable system containing the dissolved crystalline polymer has a viscosity which is substantially less than its viscosity below Tp.

  • Patent number: 6482894
    Abstract: A liquid ebonite mixture for coating includes two reactive components. The first component contains first unsaturated polymers having first functional groups capable of reaction at ambient condition either with or without a catalyst, a vulcanization agent, and a vulcanization activator. The second component contains second unsaturated polymers having second functional groups that will react with the first functional groups at ambient temperature. The first and the second unsaturated polymers must contain sufficient unsaturated backbones to allow vulcanization with the vulcanization agent. In addition, the second unsaturated polymers must be thermodynamically compatible with the first unsaturated polymers so that macroscopic phase separation will not occur and the vulcanization can happen homogeneously through out the coating.
