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