FIELD: chemistry.
SUBSTANCE: invention relates to methods of producing alkoxysilane functionalized polymers. Disclosed is a method of producing an alkoxysilane functionalized polymer, comprising adding an anionic polymerization initiator to a reactor comprising a reaction mixture comprising a conjugated diolefin monomer and a solvent, to form a living polymer through anionic polymerization; introducing alkoxysilane into a reactor for mixing with a living polymer to form an alkoxysilane functionalized polymer; adding at least one aliphatic carboxylic acid having at least 10 carbon atoms to the alkoxysilane functionalized polymer; and removing solvent from alkoxysilane functionalized polymer.
EFFECT: obtained by the disclosed method polymers have high Mooney viscosity and enable to obtain rubber mixtures with low stickiness.
