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.

Abrégé

Disclosed herein is a water-soluble copolymer formed by copolymerizing N-vinylformamide and one or more vinyl C1-C10 alkyl esters, and then hydrolyzing from 30 to 100 mol% of the formyl groups from the copolymerized units to form amino groups and from 30 to 100 mol% of the C1-C10 alkyl ester groups from the copolymerized units to form hydroxyl groups, wherein the copolymer has a unimodal molecular weight distribution as evidenced by essentially one peak in a gel permeation gradient elution chromatographic analysis. A process to produce the polymer is also disclosed.

Abrégé

Disclosed herein is a barrier layer comprising a polyvinyl amine-polyvinyl alcohol copolymer applied to a substrate as a water-soluble composition, wherein the polyvinyl amine- polyvinyl alcohol copolymer is formed by copolymerizing: (a) from 99 to 1 mol% of N-vinylformamide and (b) from 1 to 99 mol% of one or more vinyl Ci-Ci0 alkyl esters, and then hydrolyzing from 30 to 100 mol% of the formyl groups from the copolymerized units (a) to form amino groups and from 30 to 100 mol% of the Cj-Cio alkyl ester groups from the copolymerized units (b) to form hydroxyl groups, wherein the copolymer has a unimodal compositional distribution as evidenced by essentially one peak in a gel permeation gradient elution chromatographic analysis. A method of producing a barrier layer is also disclosed.

Abrégé

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.
