  • Patent number: 6291575
    Abstract: This invention relates to a phosphoric acid group-containing non-aqueous dispersion wherein polymer particles are dispersed in a solution of a macromolecular dispersion stabilizer dissolved in an organic solvent, said polymer particle being a particle of polymer comprising a phosphoric acid group-containing polymerizable unsaturated monomeric unit as a constituent component. With use of said phosphoric acid group-containing non-aqueous dispersion, there can be improved interlayer adhesivity between a metallic coating film, which is formed from a leafing type aluminum flake pigment, and another coating film adjacent thereto, without reducing the excellent effects such as dense metallic feeling of the coated surface, a chrome plating-like finish, and strong brightness feeling and strong flip-flop perperties, which are produced by such a metallic coating film.

  • Patent number: 6288138
    Abstract: A kit for dental adhesive comprising a radical polymerizable monomer having an acid group in the molecule, a photosensitizer and/or a peroxide, a water-soluble organic solvent, an organic sulfinic acid and/or a salt thereof or a barbituric acid and/or a derivative thereof, and water. The kit may further comprises a radical polymerizable monomer which has no acid group and is insoluble or hardly soluble in water, an amine compound, a silane coupling agent and a 1,3,5-triazine-2,4-dithion derivative. By using this kit, the adhesive composition can be applied directly to a dentine without conducting a pretreatment.

  • Patent number: 6251964
    Abstract: A polymer is formed from monomers including a zwitterionic monomer, a cationic monomer and a hydrophobic termonomer. The polymer may be cross-linkable. The polymer may be coated onto a surface from a liquid coating composition followed by contacting the coated surface with heparin. The double coated substrates have improved heparin activity over extended periods as compared to heparinised surfaces which are commercially available. Other anionically charged mucopolysaccharides may be used. The polymers may also scavenge heparin from treated blood to avoid use of potentially toxic heparin inhibitors. Preferably the terpolymer is formed from 2-methacryloyloxyethyl-2-(trimethylamonium)phosphate inner salt, choline methacrylate and n-dodecyl methacrylate.

  • Patent number: 6245872
    Abstract: The invention relates to the use of a mixture in a process for the adhesive securing of dental filling materials, comprising i) 10 to 90 parts by weight of at least one singly or repeatedly ethylenically unsaturated phosphoric acid ester, ii) 5 to 85 parts by weight of a solvent, iii) 0.01 to 5 parts by weight of an initiator which can form free radicals, and iv) 0 to 10 parts by weight of customary auxiliaries and additives, coating with polymerizable filling material being carried out immediately after the application of the mixture to the hard tooth substance. The invention offers the advantage that the mixture is applied to the hard tooth substance in one step and, unlike the state of the art, is coated with polymerizable filling material immediately without further aftertreatment and leads to adhesive joins comparable to those in the state of the art.

  • Patent number: 6239240
    Abstract: Disclosed is an improved method of making polymers. The method utilizes at least one ethylenically unsaturated monomer and at least one polymerizable surface active agent. The polymerizable surface active agent is capable of co-polymerization with traditional monomers and/or polymerization with itself (i.e. homopolymerization) and is preferably substantially completely consumed during the course of the polymerization. Polymers produced by the method of the present invention are well suited for use in coatings, adhesives, sealants, elastomers and the like, as they form stable films, possess excellent adhesion properties and have improved hydrolytic stability characteristics. The present invention also encompasses homopolymeric surface active agents and their use in polymerization reactions.

  • Patent number: 6187838
    Abstract: The use of polymerizable monomeric conditioning agents for treating the enamel and dentin of a tooth prior to application of a primer and subsequent application of a bonding resin, or a combination of a primer/bonding resin has been found to provide good shear bond strength on both moist and dry dentin. In addition, the contact angles provided by water on dentin conditioned with the polymerizable conditioners as compared to the non-polymerizable phosphoric acid are much lower, reflecting improved spreading over the surface of the tooth.
