FIELD: chemistry.
SUBSTANCE: described is method, consisting in successive dissolution in water of 5.0 wt % of polyvinyl alcohol with incomplete saponification degree at room temperature, heating obtained solution above 85°C and dissolution in it of 5.0 wt % of polyvinyl alcohol with deep saponification degree and 1.5-4.0 wt % of polyacrylamide. Time of film material dissolution is regulated by concentration of polyacrylamide in solution.
EFFECT: invention makes it possible to obtain homogeneous and transparent films, capable of dissolving in water within 10-30 days.
