METHOD OF MODIFYING SYNTHETIC FIBRE Russian patent published in 2008 - IPC D06M14/08 D06M13/282 D06M13/224 D06M14/14 D06M14/16 D06M15/673 

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.
