Abstract
Research results of the effect of nanodispersed ceramic powders on properties of nanocomposites based on high pressure polyethylene are given. It has been shown that the addition of the nanodispersed modifiers SiC, TiO2 leads to grinding up polyethylene grains up to the sizes of less than 0.1 μm. Herewith, an increase of the density and fastness to rubbing of polyethylene is observed, as well as the decrease in gas permeability (in 1.5 times) and water vapour permeability (in 1.7 times).
