FIELD: chemistry. ^ SUBSTANCE: composition contains a polyolefin polymer matrix containing a propylene homopolymer with MWD (molecular weight distribution) of 1.5-5.0 and copolymer of ethylene with one or more comonomers selected from alpha-olefins with 4-12 carbon atoms, having density of not more than 920 kg/m3. The weight ratio of the propylene homopolymer to the copolymer of ethylene in the polyolefin polymer matrix ranges from 95:5 to 60:40. The propylene homopolymer is polymerised in the presence of a catalyst with a single cross-linking point, where the cold xylene-soluble fraction is not more than 2 wt %. The disclosed composition has good mechanical properties, particularly impact resistance at low temperatures and bending properties, without the need to use special equipment to prepare the mixture and/or additives when producing said compositions. ^ EFFECT: articles made from the composition have good scratch resistance along with low lustre. ^ 14 cl, 3 tbl, 10 ex |
