METHOD OF PRODUCING POLYMER COMPOSITION Russian patent published in 2014 - IPC C08J3/00 B82B1/00 

FIELD: chemistry.

SUBSTANCE: invention relates to production of organofilled polymer compositions and can be used in production of construction materials and in other sectors of the economy. The first version of the method of production involves grinding 10-90 wt % organic filler to particle size of 1-20000 mcm. The organic filler is then dried to moisture content of 0-50 wt % and mixed target additives in amount of 0-20 wt %. Components are then mixed with a high-molecular weight compound in amount of 10-90 wt % and a modifying additive is added in form of nanoparticles in amount of 0.0001-50 wt %, after granulation of the composition, to the whole mass of the obtained granulate by dry charging. The second version of the method of producing the polymer composition differs from the first version in that when modifying the polymer composition based on the organic filler, the granulate is added with an amount of the modifying additive in form of nanoparticles of up to 50% to the obtained composition at the compounding step.

EFFECT: invention shortens duration of the process and reduces labour input of production and cost.
