FIELD: chemistry.

SUBSTANCE: invention refers to production of modified nanocomposite and polyolefin nanocomposite extender and can be used for materials with desired performance. Modified extender is produced by processing of natural layered silicate in aqueous suspension with two modifying additives added in turn at 60-80°C as prepared aqueous solution with concentration of 0.005-0.010 mol/l. At first aqueous suspension is added with cetyltrimethylammoniumbromide in amount equal to 25-50% of cation-exchange capacity of natural layered silicate, and when cured, added with dioctadecyldimethylammoniumbromide in amount equal to 25-75% of cation-exchange capacity of natural layered silicate. Produced suspension is cured. Extender is dewatered, washed with distilled water and dried. Trace modified extender added to polyolefin allows for considerable increase of produced composite material nanocomposite, including due to conservation of linear dimensions of initial natural layered material.

EFFECT: higher durability of produced composite material.
