Title:
酸化剤に対して改良された抵抗性を有するポリビニルアルコールフィルム
Document Type and Number:
Japanese Patent JP5657887
Kind Code:
B2
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.
