RUBBER MATERIAL WITH BARRIER MATERIAL FROM CYCLOOLEPHINE COPOLYMERS Russian patent published in 2017 - IPC C08G61/08 C09D165/00 C08J7/04 B60C1/00 

FIELD: chemistry.

SUBSTANCE: rubber material is described, provided with a barrier material in the form of a copolymer, and a tire including a rubber material. The copolymer is produced by metathesis polymerization with a ring opening a) of, at least, one first olefin monomer selected from the group consisting of cyclic olefin monomers with, at least, one endocyclic double carbon-carbon bond, in the alpha position to which there is no tertiary carbon atom substituted by A hydrogen atom, and b) of, at least, one second olefin monomer selected from the group consisting of cyclic olefin monomers with one endocyclic carbon-carbon double bond. In, at least, one alpha position, a tertiary carbon atom substituted by a hydrogen atom is present to the double bond. The copolymer is, at least, partially oxidized and the copolymer is produced without using polycyclic olefin monomers with, at least, two carbon-carbon double bonds or the amount of such monomers is less than 1 mol % in terms of the sum of the monomers.

EFFECT: proposal of alternative barrier materials for rubber products, in particular pneumatic tires, characterized by the possibility of simple, economical and effective use or possessing optimal or improved gas barrier properties.
