INITIATOR OF ANIONIC (CO)POLYMERIZATION, A PROCESS FOR ITS PRODUCTION AND A PROCESS FOR PRODUCING FUNCTIONALIZED DIENE (CO)POLYMERS WITH ITS USE Russian patent published in 2018 - IPC C07F1/02 C08F236/02 C08F36/04 C08F4/48 

FIELD: technological processes.

SUBSTANCE: invention relates to the production of synthetic rubbers, in particular to an initiator of anionic (co)polymerization, to a process for its preparation, as well as to a process for the preparation of functionalized diene (co)polymers using the initiator. Process for the preparation of an anionic (co)polymerization initiator comprising functional groups is described. Initiator is prepared by reacting an amino alcohol with an alkali metal or an organolithium compound in a hydrocarbon solvent medium. Aminoalcohol is a mixture of products obtained by the interaction of aniline and epoxyalkane.

EFFECT: vulcanizates obtained on the basis of rubbers prepared according to this method are characterized by an improved complex of physico-mechanical and elastic-hysteresis properties.
