FIELD: chemistry of polymers. SUBSTANCE: described is polymeric composition comprising from 0.5 to 99 wt %, based on total weight of (a), (b) and (c), aliphatic alpha-olefin homopolymer or copolymer, or copolymer of aliphatic alpha-olefin and non-aromatic monomer capable of being copolymerized; (b) from 0.5 to 99 wt.% based on total weight of (a), (b) and (c), hopolymer or copolymer of aromatic monovinylidene monomers, or copolymers of aromatic monovinylidene monomer and monomer capable of being copolymerized and is not aliphatic alpha-olefin and (С) from 0.5 to 99 wt.% based on total weight of (a), (b) and (c), and polymeric compatibility agent. Polymeric compatibility agent is predominantly static copolymer of aliphatic alpha-olefin and aromatic vinylidene monomer. EFFECT: improved properties of mixture. 18 cl, 7 ex, 13 tbl
