Provide is a polymer that can provide excellent toughness and weather resistance to a rubber composition and a rubber product such as a tire. The multicomponent copolymer contains a conjugated diene unit, a non-conjugated olefin unit and an aromatic vinyl unit, where a proportion of conjugated diene units bonded to a unit other than a conjugated diene unit out of the total conjugated diene units is 50% or more.

The present invention relates to a polymer composition comprising: a) 40.0 and <95.0% by weight of one or more propylene-based polymer; b) 5.0 and <65.0% by weight of one or more ethylene-based polymer; and c) 0.1 and <10.0% by weight of one or more compatibiliser composition; with regard to the total weight of the polymer composition, wherein the propylene-based polymer a) is selected from a propylene homopolymer, a propylene random copolymer, and/or a heterophasic propylene copolymer; the ethylene-based polymer b) is selected from a low-density polyethylene, a linear low-density polyethylene, and/or a high-density polyethylene; and the compatibiliser composition c) comprises one or more polystyrene-poly(ethylene-propylene) block copolymer. Such polymer compositions have good impact strength, high melt strength, good optical properties such as transparency and gloss, and are sufficiently chemically inert. They may be used for the production of transparent containers for storing potable liquids.
