Abstract: An apparatus for the liquid-phase polymerization of one or more α-olefins comprising: a first reactor selected from a loop reactor or a continuously stirred tank reactor; at least a downstream loop reactor; a connection line for transferring a polymer slurry from said first reactor to said downstream loop reactor, said connection line comprising: one or more adjacent pipes arranged at progressively increasing heights, each pipe forming with a horizontal direction (x) an angle α greater than the angle of rest of the obtained polymer; an on-off valve positioned flush with the wall of said downstream loop reactor.
