Abstract: Cold water-soluble PVOH/alkyl acrylate copolymers are provided with a substantially random distribution of monomers which is reflected in the polymer's cold water solubility, GPEC chromatograms and may be confirmed by C13 NMR. The product is particularly useful for films used in packaging and for encapsulating particulate products. Encapsulated products which may be provided include fertilizer or other agricultural products, pharmaceutical products, biomedical products and cosmetic products.

Abstract: A separator film for an electric battery is provided to substantially eliminate electric contact between an anode component and a cathode component. The film includes a vinyl alcohol copolymer with functional comonomer units such as sulfonic acid functionalized units or salts thereof. The films are desirable for use in battery separators because they exhibit superior resistance to degeneration by oxidation, enabling the manufacture of batteries with improved conductivity, longer discharge times, and longer cycle lives.

Abstract: A water-soluble film which comprises a saccharide component and a vinyl alcohol resin component, where the vinyl alcohol resin may include functional comonomer units such as sulfonic acid functional groups or salts thereof. Preferred are polyvinyl alcohol/2-methylacrylamido-2 methyl propane sulfonic acid resins (PVOH/AMPS) which may be purchased commercially with relatively higher or relatively lower characteristic viscosity. The films exhibit superior resistance to aggressive oxidizing chemicals and remain soluble in water after prolonged exposure thereto. The films are particularly useful for unit-dose packaging of chlorine-containing pool chemicals, such as trichloroisocyanuric acid.

Abstract: Disclosed herein is a process to produce a film comprising poly(vinyl alcohol), wherein the poly (vinyl alcohol) solution has been purified utilizing an ion exchange resin. An approximate 50 micrometer thick film produced from the purified aqueous poly(vinyl alcohol) solution has an APHA color value of 50 or less after the film has been heated at 150° C. for 60 minutes.
