FIELD: chemistry. n SUBSTANCE: method includes contacting of (i) C 4 -C 7 isomonoolefin and p-alkylstyrole, or (ii) C 4 -C 6 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 x H y F 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. n 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. n 23 cl, 25 tbl, 148 ex, 3 dwg |
