FUNCTIONALISED DIENE-BASED ELASTOMER AND RUBBER COMPOSITION CONTAINING SAME Russian patent published in 2015 - IPC C08C19/25 C08C19/44 C08L9/06 C08L15/00 C08L19/00 B60C1/00

Abstract RU 2565706 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a functionalised diene-based elastomer and to a composition based thereon. The functionalised diene-based elastomer is 75-95 wt % monofunctional elastomer which carries at one chain end a silanol functional group or a polysiloxane block with a silanol end without functionalisation at the other end, and 5-25 wt % of the elastomer is bonded or star-branched by tin.

EFFECT: invention reduces cold flow without deterioration of processing properties and hysteresis properties.
