FIELD: chemistry.
SUBSTANCE: invention relates to production technology of films having increased fire-resistance, particularly to films based on polyvinyl alcohol and can be used in various industries and economics for fireproof modification of the materials based on them. According to the method methylphosphite borate is preliminary mixed with plasticiser at the ratio 1:4 and 1-5% of aqueous solution of polyvinyl alcohol is added. Thereafter, films are moulded and dried at the ambient temperature. Glycerin, glycol alcohol or diethylene glycol is used as a plasticiser.
EFFECT: invention allows simplifying modification, increasing reliability and fire resistance of films.
