  • Patent number: 5908877
    Abstract: A water dispersible powder composition is provided. The powder composition contains at least one film-forming polymer having at least one functional group and at least one reactive component that reacts to form a non-ionic bond with the polymer functional group following dispersion of the powder composition in water. The reaction between the polymer particles in the admixture and the reactive component renders the resulting coating water-resistant. The powder composition of this invention is useful for producing water-resistant coatings.

  • Patent number: 5814374
    Abstract: An aqueous coating composition having low VOC is provided. The invention provides excellent hardness and resistance properties in films formed from binders having glass transition temperatures below ambient temperature. The improvement in film properties comes from the binding of functionalized polyvinyl alcohol to a complementary functionalized latex binder. The low VOC compositions of this invention are useful for a variety of coatings including paints, stains, varnishes, mastics and adhesives.

  • Patent number: 5759358
    Abstract: Processes are provided for producing a pure grade of acrylic acid having residual aldehyde levels under 10 parts per million. The processes apply selected groups of amines sequentially and, preferably, continuously in selectively reducing, for example, acrolein and furfural, and may be advantageously conducted in the presence of maleic acid and maleic anhydride impurities.
