Abstract

A process is provided for the manufacture of polyvinyl alcohol, having an APHA color of equal to or less than about 10, by polymerizing a vinyl acetate monomer to form polyvinyl acetate and then hydrolyzing the polyvinyl acetate to form polyvinyl alcohol wherein the vinyl acetate monomer is characterized as having an inhibitor level of equal to or less than about 10 ppm, preferably less than about 5 ppm, more preferably less than about 3 ppm, even more preferably less than about 1 ppm.

Abstract

A chemical delivery product for delivering an oxidizing chemical into an aqueous system is disclosed. For instance, in one embodiment, a substrate containing an oxidizing chemical, such as trichloroisocyanuric acid, is coated with a water soluble polymer in order to prevent the oxidizing chemical from degrading prior to use and in order to facilitate handling. In accordance with the present disclosure, a neutralizing agent is contacted with the substrate in order to prevent the substrate from degrading the water soluble coating. In an alternative embodiment, a package is formed from a water soluble film forming composition combined with a base.

• C11D 7/28 - Organic compounds containing halogen

Abstract

A water-soluble film which comprises a saceharide 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.
