METHOD OF CONTINUOUS GAS PHASE POLYMERIZATION OF ALFA- OLEFIN(S) Russian patent published in 1999 - IPC

FIELD: gas phase polymerization. SUBSTANCE: polymerization of monomers is carried out in fluidized- bed reactor in which metallocene catalyst is used and where recirculating stream which comprises liquid and gas phase in introduced into reactor so that weight percent content of liquid in terms of total weight of recirculating stream exceeds 2 wt % and said recirculating stream contains dew pint increasing component in amount of more than 2.0 mol %. EFFECT: greater efficiency with respect to polymer and wide range of polymer having improved characteristics. 19 cl, 3 ex, 5 tbl
