FLUORINATED POLYAMIDE COMPOSITION WITH REDUCED FLAMMABILITY Russian patent published in 2019 - IPC C08L77/00 C09K21/08 C09K21/14 

FIELD: chemistry.

SUBSTANCE: invention relates to composite materials with reduced flammability, including a polymer base and a filler – flame retardant, and can be used for the production of molded products – filaments, films and sheets, monolithic molded samples. Fluorinated polyamide composition with low flammability is described, including PA-6 polyamide and a flame retardant – polyfluorinated alcohol previously adsorbed on montmorillonite, in which 1,1,9-trihydroperfluorononanolol-1 is used as polyfluorinated alcohol, in the following ratio of components, % mass.: montmorillonite – 60.0; 1,1,9-trihydroperfluorononanolol-1 – 40.0; when the ratio of components in the composition, % mass.: polyamide PA-6 – 99.7–99.0; montmorillonite with adsorbed polyfluorinated alcohol – 0.3–1.0.

EFFECT: technical result of the claimed polyamide composition is an increase in the duration of its fire and heat protective effectiveness.
