  • Patent number: 6900262
    Abstract: The present invention generally provides a method for producing an exfoliated nanocomposite. The method involves charging to water, as the continuous phase, monomers, polymerizable surfactant, and water-soluble initiator. The monomers are allowed to polymerize under agitation to form an emulsion of polymers, and the polymerizable surfactant is bound to the polymers so formed, with an ionic end of the polymerizable surfactant extending from the polymers to provide surface charges. Thereafter, a suspension of nanofillers in water is charged to the emulsion. The nanofillers are oppositely charged from the ionic end of the polymerizable surfactant such that they electrostatically bind to the polymers within the emulsion. The water is subsequently decanted to produce a nanocomposite with an exfoliated structure.

  • Patent number: 6852803
    Abstract: A polymer dispersant for pigments based on a graft copolymer which contains a new type of urea functional group as the pigment anchoring group. The urea groups are attached to the graft copolymer by a convenient method which involves reaction of hydroxyl functional groups built in the graft copolymer with a diisocyanate that is capped at one end with ammonia or a primary or secondary amine. The reaction is convenient and clean. Substantial crosslinking or gelling of the polymer can be easily avoided by judicious selection of appropriate ingredients and processing conditions. These materials are effective in dispersing and stabilizing a wide range of pigments in solvent based systems and are particularly useful in forming pigment dispersions that are used in a variety of solvent borne coating compositions for automobiles and trucks, where they provide improved efficiency of pigment use, lower paint viscosity, and reduced emission of volatile organic solvent.

  • Patent number: 6822039
    Abstract: The invention concerns modified hydrophobic polyelectrolytes by amide formation of a hydrophilic skeleton by n-alkylamines whereof the alkyl chain comprises 6 to 22 carbon atoms. Preferably, the amide formation is obtained by di-n-dodecylamine. The hydrophilic skeleton is preferably a sodium polyacrylate or polyacrylic acid corresponding to a statistical acrylate-AMPS copolymer. Said polymers can be used for stabilising direct or invert emulsions likely to be destabilised or inverted by a modification in the degree of salinity of the aqueous phase or a pH modification. The invention is particularly useful for stabilising oil drilling fluids or the like in particular drilling, fracturation, acidification or completion fluids.

  • Patent number: 6811817
    Abstract: The invention discloses improvements in the so-called coated thermal flow process for reducing the pattern dimension of a patterned resist layer on a substrate to accomplish increased fineness of resist patterning, in which a coating layer of a water-soluble resin formed on the patterned resist layer is heat-treated to effect thermal shrinkage of the coating layer with simultaneous reduction of the pattern dimension followed by removal of the coating layer by washing with water. The improvement of the process is obtained by using an aqueous coating solution admixed with a water-soluble amine compound such as triethanolamine in addition to a water-soluble resin such as a polyacrylic acid-based polymer.

  • Patent number: 6806301
    Abstract: A single fluid lithographic printing ink composition includes a hydrophobic phase and a hydrophilic fluid phase. The hydrophilic fluid phase contains water or a liquid polyol or both. The hydrophobic phase contains a hydrogen bonding vinyl polymer that can hydrogen bond with the hydrophilic fluid phase. The vinyl polymers are preferably branched, but remain soluble in the hydrophobic phase. The invention provides stable inks that can be used as single fluid inks with excellent fountain stability and resistance to toning.
