FIELD: chemistry.
SUBSTANCE: method for obtaining of organomodified montmorillonite with polyfluoroalkyl groups involves treatment of natural montmorillonite with polyfluorinated alcohol with ultrasonic dispersion in a solvent at heating and ultrasound frequency of 40 kHz, followed by modified montmorillonite separation, washing and drying. The treatment is carried out with 1,1,3-trihydroperfluoropropanol-1 in n-heptane at 30°C at the following component ratio, wt part.: montmorillonite - 100.0; 1,1,3-trihydroperfluoropropanol-1 - 8.7; N-heptane - 200.0.
EFFECT: increased hydrophobicity of organomodified montmorillonite and stability of forming organomineral complexes, which allows to provide polymers with improved thermal, light, wear and hydrolytic stability.
