FIELD: chemistry.
SUBSTANCE: method involves grafting onto a synthetic fibre a phosphorous containing monomer at room temperature for a period of 15 minutes and subsequent drying. The phosphorous containing monomer used is a 50% water solution of phosphorous-boron-containing methacrylate, neutralised with a solution of ammonia to pH 7. Grafting is done in the presence of a sodium persulphate initiator, taken in quantity of 1-5% mass of phosphorous-boron-containing methacrylate.
EFFECT: simplification of the technological process of obtaining modified synthetic fibre; their increased fire resistance; strength and resistance to thermo-oxidative breakdown.
