FIELD: polymerization processes. SUBSTANCE: invention provides method for continuous gas-phase fluidized-bed polymerization of olefin monomer(s), in which recycle gas stream escaping reactor is divided into two streams. The first stream cooled to gas-condensation temperature is returned into reactor, immediately into fluidized bed in a manner that, at any moment, condensed liquid continuously enters fluidized bed at minimum hourly intake 10 l per 1 cu.m fluidized bed material. The second stream, omitting above- indicated cooling/condensation stage, is passed through heat-exchanger and then returned into reactor. Continuous feeding of liquid into reactor allows reducing and even eliminating contamination problems possibly arising when known methods of gas-phase olefin polymerization processes are conducted. EFFECT: enhanced process efficiency. 9 cl, 3 dwg, 4 ex
