PRODUCTION METHOD OF MODIFIED EXTENDER FOR POLYOLEFIN NANCOMPOSITES, MODIFIED EXTENDER AND POLYOLEFIN NANCOMPOSITE Russian patent published in 2009 - IPC B82B3/00 C08J3/205 C08L23/00 C08K9/04 C08K3/34 C01B33/44 C09C1/42 

FIELD: chemistry.

SUBSTANCE: invention refers to production of modified extender for nanocomposite, and to polyolefin nanocomposite, and can be used for production of materials with preset performance. Production of modified extender includes as follows. Natural layered silicate is processed in aqueous suspension with modifying additive in amount equal to 25-75% of cation-exchange capacity of natural layered silicate. Herewith modifying additive is dioctadecyldimethylammonium bromide added to suspension as aqueous solution concentrated no more than 8.5×10^-3 mol/l at 60-80°C. Prepared suspension is cured. Extended is dewatered, washed with distilled water and dried. Trace modified extender added to polyolefin allows for considerably increased durability of produced composite material nanocomposite, including due to conservation of linear dimensions of initial natural layered material.

EFFECT: increased durability of produced composite material.
