POLYMERS, FUNCTIONALISED WITH NITRILE COMPOUNDS WITH PROTECTIVE AMINOGROUP Russian patent published in 2015 - IPC C08C19/00 C08C19/22 C08F2/00 C08F2/06 C08F36/06 C08F4/44 C08F4/54 

Abstract RU 2538253 C2

FIELD: chemistry.

SUBSTANCE: invention relates to obtaining functionalised cis-1,4-polydienes, which are useful, especially, in tyre-production. Method of obtaining functionalised polymer includes the following stages: (i) polymerisation of conjugated diene monomer with coordination catalyst to form reactionable polymer and (Iii) interaction of reactionable polymer with nitrile compound, containing protective aminogroup.

EFFECT: invention makes it possible to obtain functionalised cis-1,4-polydienes, possessing reduced properties of hysteresis and cold flow.
