ABSTRACT:
In order to preserve the solubility of films and moldings of polyvinyl alcohol in cold water even under the action of an aggressive atmosphere, in particular a strongly acidic atmosphere, the thermoplastically processable polyvinyl alcohol composition used for the preparation of the films and moldings is stabilized by the addition of a water-soluble polymer or copolymer which is composed to the extent of at least 70% by weight of monomer units which are carboxylic acid amides at least monosubstituted on the amido nitrogen. N-vinylpyrrolidine, N-vinyl-N-methylacetamide and the alkali metal salts or the ammonium salts of 2-acrylamido-2-methylpropanesulfonic acid have proved to be particularly suitable representatives of this group of compounds.
