FIELD: chemistry of organophosphorus compounds.
SUBSTANCE: invention relates to compounds with the bond C-P, namely to phosphorus-boron-containing methacrylate that can be used as inhibitor of combustion of polyvinyl alcohol-base film materials. Invention describes phosphorus-boron-containing methacrylate of the following formula: 
wherein n = 4-8. Polyvinyl alcohol films modified with indicated phosphorus-boron-containing methacrylate shows the enhanced refractoriness, rupture strength up to 206 kgf/cm2, water absorption up to 240% and relative elongation up to 12%.
EFFECT: valuable properties of substance.
