摘要：The invention relates to a method and an apparatus for the polymerization ofgaseous olefins, in particular of ethylene and at least one &agr;-olefin, in the gas phase ina stirred or fluidized, catalyst-containing polymerization zone () and at least one
decompression zone () downstream of the polymerization zone (). The mixture of solid(co)polymer and unreacted monomers leaving the polymerization zone () flows through asettling zone, in particular in the form of a settling leg (), before the decompressionzone.
