METHODS OF POLYMERISATION Russian patent published in 2009 - IPC C08F2/06 C08F210/12 C08F210/10 

FIELD: chemistry.

SUBSTANCE: invention relates to methods of polymerisation for obtaining polymers using reactor system with boiling reservoir and solvents, which include hydrofluorocarbons. Method of polymerisation is described, which includes contacting of catalytic system, which consists of one or more Lewis acids, and one or more initiators, solvent, which includes one or more hydrofluorocarbons (HFC), and (i)C₄-C₇ isomonoolefin and para-alkyl styrene or (ii) C₄-C₆ isoolefin and multiolefin as co-monomers with formation of polymerisation medium, where polymerisation medium evaporates during polymerisation and where contacting is takes place in reactor system with boiling reservoir, solvent efficiently dissolving catalytic system and monomers, but relatively badly dissolving obtained copolymer.

EFFECT: reduction of particle agglomeration and reactor clogging, increase of productivity of polymers with high molar weight.
