  • Patent number: 6051562
    Abstract: An oil in water emulsion comprises a continuous aqueous phase and a discontinuous oil phase which is either a hydrophobic liquid which is immiscible with the aqueous phase or is a solid phase obtained by providing an emulsion in the aqueous phase of a solution of potentially solid material in the hydrophobic liquid and converting this solution to a solid phase, and the emulsion is stabilized by the inclusion of water-soluble stabilizing polymer in the aqueous phase and oil solubilizing stabilizing material, generally polymer, in the oil phase. The or each polymer is preferably a copolymer of hydrophilic and hydrophobic groups, preferably being formed by copolymerization of water-soluble monomer and oil-soluble monomer that provide the desired groups in the polymer without further reaction. Partially hydrolyzed polyvinyl alcohol can be used as the water-soluble polymer.

  • Patent number: 5741828
    Abstract: The present invention is directed to a coating composition which includes a component A and component B. Component A is either an emulsion or dispersion having a hydrophobic elastomer stabilized with at lease one emulsifier. Component B is a dispersion or solution of a hydrophilic polymer which is insoluble in water, swellable in water and soluble in one or more water-miscible solvents. The hydrophobic elastomers may be polymers or copolymers of butadiene, isoprene, chloroprene, styrene, acrylonitrile, ethylene, propylene, isobutylene, alkylacrylates and alkylmethacrylates; polyrethanes, polyureas, polysiloxanes, elastomeric polyamides and polyesters. The hydrophilic polymers may be segmented polyurethanes, segmented polyures, segmented polyesters, partially hydrolyzed poly(vinyl acetate), partially hydrolyzed polyacrylonitrile, partially aminolyzed polyacrylonitrile, and ethylene glycol monomethacrylate.

  • Patent number: 5733621
    Abstract: An adhesive roofing tape is based on a combination of brominated butyl rubber and EPDM. A non-diene block terpolymer is interspersed in the cross-linked polymer network. A plasticizer and tackifier are included to provide resiliency and permanent tack. An important aspect of the invention is to use a high molecular weight polyisobutylene plasticizer and a peroxide curing system. Rapid crosslinking without concomitant rapid degradation of the brominated butyl rubber occurs and some limited degradation of the plasticizer contributes to surface tack. A method of making the adhesive roofing tape is also provided.

  • Patent number: 5726235
    Abstract: An aqueous coating composition wherein fine grains coated with water soluble resin composed of three monomers are contained in aqueous medium, each of said fine grains are composed of aqueous resin of ethylenically unsaturated monomer and aqueous colloidal silica, which are coexistent each other. Therefore, the aqueous coating composition is superior in not only contamination resistance, but also waterproof and weatherproof. The paint film formed by the above aqueous coating composition is excellent in its strength. Accordingly, this aqueous coating composition is useful for a coating base of exterior type coating material.

  • Patent number: 5712346
    Abstract: Rubber articles are coated with a powder-free coating; the power-free/non-tacky coating comprises a copolymer formed by the sequential polymerization of two mixtures of monomers comprising styrene, alkyl acrylates, acrylic acid, methacrylic acid, and a silicone oligomer. The sequential polymerization of the two monomer mixtures produces a core copolymer surrounded by a shell copolymer, in which the two copolymers have differing glass transition temperatures.
