MULTICOMPONENT COPOLYMER, RUBBER MIXTURE AND TIRE Russian patent published in 2018 - IPC C08F236/04 C08F236/10 C08F236/06 C08F212/08 C08L9/06 B60C1/00 

FIELD: chemistry.

SUBSTANCE: invention relates to a multicomponent copolymer, a rubber mixture and a tire. Multicomponent copolymer containing a conjugated diene unit (1,3-butadiene and/or isoprene), a non-conjugated olefin (ethylene) unit and a vinyl aromatic unit (styrene) is described. Main chain of a multicomponent copolymer consists only of acyclic structures. Content of cis-1,4-bonds in the conjugated diene monomer on the whole is 50% or more.

EFFECT: technical result is the preparation of a polymer to improve the strength and weather resistance of rubber articles such as tires and rubber blends, further having a low crystallinity.
