ALPHA-MONOOLEFIN POLYMERISATION PROCESS IMPROVED BY CONTINUALLY ADDING A DIALKYLALUMINIUM HALIDE AND CONDUCTING THE PROCESS AT 0.1 TO 5.0 O C ABOVE THE DEW POINT OF THE RECYCLE GAS

Highly stereospecific olefin polymers are obtained in enhanced yield in a continuous gas-phase fluid bed process for polymerizing alpha monoolefins employing a catalyst system comprising (a) a solid titanium-containing procatalyst, (b) an organoaluminum activator compound, and (c) a selectivity cont...
