Abstract

The properties of polyvinyl alcohol films containing biologically active polymer additives and modifying reagents are a function of the supermolecular structure, determined by the composition of the spinning compositions. The variable character of the water vapor permeability of the films caused by the stresses that arise in the structure of the biologically active polyvinyl alcohol film in structural transitions that lead to variable water vapor permeability conditions, was established.
