Abstract: A process is disclosed for the polymerization of olefins in gas phase carried out in a reactor having two interconnected polymerization zones, a first zone (riser) and a second zone (downcomer), wherein the growing polymer particles: a) flow through the riser under fast fluidization conditions established by feeding a mixture of gas and liquid; b) leave the riser and enter the downcomer, through which they flow downward in a densified form; c) leave the downcomer and are reintroduced into the riser, thus establishing a circulation of polymer between the riser and the downcomer; and wherein the reactor is operated at a temperature which is between 0° C and 5° C above the dew point of the riser gas at the operating pressure, so that in the riser, besides the growing polymer particles and gas flow, an amount of liquid is also present.
