METHODS OF POLYMERISATION Russian patent published in 2008 - IPC C08F210/10 C08F210/14 C08F236/04 C08F2/06 C08F4/14 C08F4/16 

FIELD: chemistry.

SUBSTANCE: method includes contacting of (i) C₄-C₇ isomonoolefin and p-alkylstyrole, or (ii) C₄-C₆ isoolefin and multiolefin, one or more Lewis acid, one or more initiator, and solvent, including one or more hydrofluorocarbons (HFC) in reactor. As hydrofluorocarbon, compounds, represented with general formula C_xH_yF_z, are used, where x is an integer from 1 to 40, and y and z are integers. Solvent additionally includes non-reactive olefin, one or more other hydrocarbons, and/or inert gas.

EFFECT: reduction of particle agglomeration and reactor blocking, without degradation of process parameters, conditions or components, productivity of reactor capacity and ability to produce polymers with great molecular weight.
