Abstract: A process 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 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 the growing polymer particles flow downward in a densified form; and c) leave the downcomer and are reintroduced into the riser, thereby establishing a circulation of polymer between the riser and the downcomer; the reactor is operated at a temperature between 0° C. and 5° C. above the dew point of the riser gas at the operating pressure, and in the riser, besides the growing polymer particles and gas flow, an amount of liquid is present.

Abstract: Process for the preparation of heterophasic propylene copolymer compositions (RAHECO) made from or containing a random propylene copolymer (RACO) and an elastomeric propylene copolymer (BIPO), the process being carried out in a reactor having two interconnected polymerization zones, a riser and a downcomer, wherein growing polymer particles: (a) flow through the first polymerization zone, the riser, under fast fluidization conditions in the presence of propylene and of ethylene or an alpha-olefin having from 4 to 10 carbon atoms, thereby obtaining the random propylene copolymer (RACO); (b) leave the riser and enter the second polymerization zone, the downcomer, through which the growing polymer particles flow downward in a densified form in the presence of propylene and of ethylene or an alpha-olefin having from 4 to 10 carbon atoms, wherein the concentration of ethylene or of the alpha-olefin in the downcomer is higher than in the riser, thereby obtaining the elastomeric propylene copolymer (BIPO); and (c) leave the downcomer and are reintroduced into the riser, thereby establishing a circulation of polymer between the riser and the downcomer.
