SYNTHESIS OF LIQUID POLYMER AND FUNCTIONALISED POLYMER Russian patent published in 2012 - IPC C08F4/48 C08F4/46 C08F36/04 C08F36/06 C08F2/06 B60C1/00 C08L9/00 

FIELD: chemistry.

SUBSTANCE: invention relates to methods of producing a polymer, having at least one functional terminal group, and a liquid polymer dispersed therein. The invention also relates to a composition and a coating containing the obtained polymer product. The method involves: (a) producing a 'living' polymer, where production of said 'living' polymer is initiated based on an anionic mechanism, and said polymer contains a cation; (b) adding a functional initiator precursor of the formula FI-H, where H is hydrogen and FI is a functional group, said H terminates said 'living' polymer resulting in a liquid polymer, and FI and said cation form a functional initiator; (c) adding a monomer, where said functional initiator initiates anionic polymerisation of said monomer; and (d) terminating the polymerisation reaction initiated at step (c). Steps (a) through (c) may be conducted in a single reactor, allowing a liquid polymer to be dispersed in a functionalised polymer in a single polymerisation step.

EFFECT: liquid polymer does not have to be handled separately and processing efficiency is improved.
