FIELD: chemistry.
SUBSTANCE: invention relates to polymeric nanocompositions intended for obtaining film materials that provide protection against UV radiation and photochemical ageing. Composition contains polyolefin or a olefin copolymer and UV-absorber. UV-absorber is nanosized silicon carbide that is single-phase polycrystalline and consisting of synthetic silicone carbide (SiC) with structure of moissanite polytype 6H with average particle size 34±3 nm in the amount of 0.1-1.5 wt%. Polymeric nanocomposition enables to obtain film materials with wide spectral range of absorption wave UV radiation (200-420 nm).
EFFECT: dangerous UV radiation range (200-290 nm) is absorbed at 100-90 %.
