    摘要： The invention relates to a process for the continuous polymerization α-olefin monomers comprising: feeding the α-olefins to a vertically extended reactor for the continuous fluidized bed polymerization of α-olefin monomers, wherein the reactor comprises a distribution plate and an integral gas/liquid separator, withdrawing the polyolefin from the reactor, withdrawing fluids from the reactor, cooling the fluids to below their dew point, resulting in a bottom recycle stream, (5) introducing the bottom recycle stream, separating at least part of the liquid from the bottom recycle stream, feeding a liquid phase to an external pipe, adding a solid polymerization catalyst to the liquid phase in the external pipe and (9) feeding a slurry stream comprising the prepolymer and/or polymer into the reactor, wherein the prepolymer and/or polymer are present in the slurry stream in an amount of 0.01 to 99 wt % based on the total slurry stream upon introduction into the reactor.
