METHOD OF PRODUCING NANOCOMPOSITE MATERIAL BASED ON NONPOLAR OR LOW-POLARITY POLYMERS AND NANOFILLER Russian patent published in 2012 - IPC B82B3/00 C08J3/20 B29B13/00 C08L101/12 C08K9/00 C08K9/04 C08K3/34 

Abstract RU 2441835 C2

FIELD: chemistry.

SUBSTANCE: invention is related to the method of producing nanocomposite material and it can be used in packaging, wire (non-flammable insulation of electrical wires) and other industries. The method includes melt mixing of low density polyethylene and layered silicate. As layered silicate, natural montmorillonite is used being modified with quaternary ammonium salt. Before melt mixing, low density polyethylene is preliminarily shearly degraded at high temperature in a single screw dispergator with three temperature zones.

EFFECT: pre-treatment of the polymer helps to overcome incompatibility of the filler and material polymer base and, consequently, to significantly enhance the mechanical properties of the nanomaterial being produced.
