METHOD OF PREPARING RUBBER MIXTURES AND RUBBER Russian patent published in 2011 - IPC C08J3/20 C08L9/00 C08L9/02 C08C19/04

Abstract RU 2414486 C2

FIELD: chemistry.

SUBSTANCE: unsaturated polyketone which contains carbonyl groups and double carbon-carbon bonds is added to the rubber mixture. Unsaturated polyketone has average molecular weight of 19000-120000. Unsaturated polyketone is added to the rubber mixture in amount of 51-100 wt % of the total amount of high-molecular weight carbon-chain rubber and unsaturated polyketone in the mixture. Unsaturated polyketone is obtained through oxygenation of diene rubber with nitrogen monoxide. The rubber mixture is vulcanised.

EFFECT: method increases bonding strength between coating rubber and metal cord and fatigue strength of the rubber.
