FIELD: chemistry.

SUBSTANCE: polyolefin compositions and the production of cast products from them. A polyolefin composition is proposed for producing a cast product, containing from 55 to 95 wt.% of a multimodal statistical copolymer of propylene and butene, having a PTR₂ from 1.0 to 20.0 g/10 min, the butene content in which is from 1.5 to 8 .0 wt.% obtained using a metallocene, and from 5 to 45 wt.% of an ethylene-based plastomer having a density from 860 to 905 kg/m³, PTR₂ from 0.3 to 30 g/10 min, obtained with using metallocene; a method for producing the proposed composition, a cast product made from the proposed composition, and the use of the proposed polyolefin composition for the manufacture of a cast product.

EFFECT: production of cast products with good impact characteristics, as well as good optical properties, which include low turbidity and good optomechanical properties.
