  • Patent number: 5480720
    Abstract: An adhesive composition includes from about 30 weight percent to about 70 weight percent solids dispersed in an aqueous medium. The solids include from about 60 weight percent to about 97.9 weight percent of a polymer having a glass transition temperature of about -40.degree. C. to about 10.degree. C. and including first repeating units derived from an alkyl (meth)acrylate monomer, a vinyl ester monomer, a styrenic monomer or a mixture thereof and second repeating units derived from a hydroxyalkyl (meth)acrylate monomer, a monoethylenically unsaturated nitrogenous monomer or a mixture thereof; from about 2 weight percent to about 30 weight percent of a polyfunctional epoxy resin including two or more epoxide groups per molecule; from about 0.1 weight percent to about 10 weight percent of a polyfunctional curing agent including two or more amino groups or amido groups per molecule; and from about 0.01 weight percent to about 30 weight percent of a metal salt.

  • Patent number: 5281654
    Abstract: This invention is directed to a polyurethane mixture. More particularly, there is provided a mixture polyurethanes comprising a first polyurethane with at least two end groups, where each end group comprises a terminal isocyanate and a polyether; a second polyurethane with at least two end groups, where each end group comprises a terminal isocyanate group and a non-functional group; and a third polyurethane with at least two end groups, where one end group comprises a terminal isocyanate and a polyether and one other end group comprises a terminal isocyanate and a non-functional group. A method for improving the sag resistance of an aqueous composition is also provided. This method permits the formulation of aqueous compositions which resist the tendency to sag. The polyurethane mixture of this invention is useful for thickening aqueous compositions such as paints, coatings, cosmetics, personal care items, hair shampoos and conditioners, cleaners, and the like.

  • Patent number: 5137571
    Abstract: A method is provided for improving thickeners used in aqueous system. The improvement is directed to the elimination of organic cosolvents which are conventionally added to aqueous solutions of certain hydrophobic thickeners. This method involves the reversible complexation of cyclodextrin compounds with hydrophobic moieties on the thickener molecule to suppress the viscosity of the aqueous solution containing the thickener so that such the solution can be easily handled. This is followed by decomplexing the cyclodextrin from the thickener to permit the thickener to perform its intended function.
