METHOD OF COMPOSITE MATERIAL PRODUCTION ON BASIS OF POLYOLEFINS AND CARBON NANOTUBES Russian patent published in 2017 - IPC C08J3/205 C08K3/04 C08L23/00 B82B3/00 B82Y30/00 C08F292/00 

FIELD: nanotechnology.

SUBSTANCE: invention relates to the method of inserting carbon nanotubes into polyolefins to produce nanocomposites used in the production of various products from polymer composite materials. The method of composite material production on the basis of polyolefins and carbon nanotubes - CNTs with high content of CNT=5-20 wt % is carried out in sequence. At first a fine suspension of pretreated CNT is put into a polymerization reactor at room temperature. The pretreatment of CNT is the milling and sifting, warming and vacuum treatment at elevated temperature. Then the co-catalyst is inserted while stirring - the trialkylaluminum and the suspension of the finely supported titanium-magnesium catalyst. The reaction mixture is heated with stirring to 50-80°C, a comonomer or a mixture of comonomers is introduced in case of copolymerization up to the set pressure and the required amount of the polymer is brought at a constant temperature and pressure. The invention provides a homogeneous distribution of carbon nanotubes in the polyolefin matrix.

EFFECT: obtaining a homogeneous distribution of carbon nanotubes in the polyolefin matrix.
