Abstract

Unsatd. hydrocarbon monomers are polymerised in two stages in the presence of a Group Va or VIa catalytic oxide dispersed on an inert particulate support activated by AlH3 or alkyl aluminium. Preformed polymer agglomerates are formed by contacting the monomer feed with catalyst and a minimal amt. of inert hydrocarbon solvent. The prepoylmers are then formed to the desired size in a gas phase polymerisation zone, pref a fluidised bed, at 25-90 degrees C., and 21-105 kg./cm2. The monomers are pref. alpha-olefins esp. ethylene and/or propylylene.
