Abstract: A continuous bulk polymerization and esterification process includes continuously charging into a reaction zone at least one ethylenically unsaturated acid-functional monomer and at least one linear or branched chain alkanol having greater than 11 carbon atoms. The process includes maintaining a flow rate through the reaction zone sufficient to provide an average residence time of less than 60 minutes and maintaining a temperature in the reaction zone sufficient to produce a polymeric product incorporating at least some of the alkanol as an ester of the polymerized ethylenically unsaturated acid-functional monomer. The polymeric product is used in various processes to produce water-based compositions including emulsions and dispersions such as oil emulsions, wax dispersions, pigment dispersions, surfactants and coatings which contain the polymeric product.

Abstract: A polyol blend, comprising a low-Tg high-hydroxyl number acrylic copolymer and a high-Tg low-hydroxyl number acrylic copolymer, is disclosed. The low-Tg and high-Tg acrylic copolymers each comprise a hydroxyalkyl acrylate or methacrylate, and a non-hydroxy moiety-containing alkyl methacrylate. The low-Tg copolymer has a hydroxyl number of about 112 to about 187, a number-average molecular weight of about 1500 to about 6000, a polydispersity value of no greater than about 5, and a Tg of about -10.degree. to about 20.degree. C. The high-Tg copolymer has a hydroxyl number of about 35 to about 112, a number-average molecular weight of about 2000 to about 8000, a polydispersity value of no greater than about 5, and a Tg of about 25.degree. to about 100.degree. C. Also disclosed are coating compositions comprising the polyol blend.

Abstract: This invention relates to pigmented curable silicate compositions having better pigment dispersions as evidenced by improved color uniformity, hiding power, lower viscosity and consistency. The aqueous compositions contain water-soluble or -dispersible silicate glass, pigment and a base having a basicity greater than that of the silicate glass. Preferred compositions also contain a water-soluble latent insolubilizing agent.

Abstract: This invention relates to pigmentary hardener-containing curable silicate compositions having improved water resistance, wherein the pigmentary hardener has the formula M.sub.x M.sub.y 'O.sub.z where M is a divalent or trivalent metal ion, M' is an ion of a metal from Groups III, IV or VIB of the Periodic Table of Elements, provided M and M' are not the same metal ion, x is 1 or 2, y is 1, 2 or 3 and z is an integer the value of which satisfies the oxidation state of the pigmentary hardener.

Abstract: Curable one-package compositions which form products having excellent water resistance as well as other desirable properties are prepared by forming aqueous solutions of water-soluble silicates and water-soluble borate latent insolubilizers selected from the group consisting of alkali metal or quaternary ammonium borates, having dispersed therein certain inorganic pigments, preferably TiO.sub.2. These curable compositions may be employed in a number of applications such as, for example, coatings, castings and moldings, but they are particularly useful in protective and decorative applications.

Abstract: Curable one-package compositions which form products having excellent water resistance as well as other desirable properties are prepared by forming aqueous solutions of water-soluble silicates and water-soluble zincate latent insolubilizers selected from the group consisting of alkali metal or quaternary ammonium zincates having dispersed therein certain inorganic pigments, preferably TiO.sub.2. These curable compositions may be employed in a number of applications such as, for example, coatings, castings and moldings, but they are particularly useful in protective and decorative applications.
