PHOSPHORUS-CONTAINING FIRE RETARDANTS Russian patent published in 2014 - IPC C09K21/12 C09K21/14 C08K5/5397 C08K7/14 C08L77/00 

FIELD: chemistry.

SUBSTANCE: invention relates to phosphorus-containing fire retardants, particularly, but not exclusively, for glass-filled polyamide resins. A fire-resistant polymer composition contains a main polymer (A), where the main polymer (A) includes a glass-filled polyamide, and a benzyl-substituted organophosphorus compound (B). The organophosphorus compound (B) is present in amount of about 10 wt % to about 30 wt % with respect to the amount of the fire-resistant polymer composition.

EFFECT: said organophosphorus compounds, especially if coupled with specific synergists, are effective fire retardants for thermoplastic polymers, including polyamides, especially glass-filled polyamides.
