Abstract

Vinyl monomers particularly alpha-olefins are polymerized in a fluidized bed of solid particles of growing polymer, in the absence of liquid media and in the presence of a catalyst consisting of an organo-metallic compound and a transition metal compound absorbed on the solid polymer particles. The polymer particles are kept in the fluidized state by circulating through them a gaseous stream comprising the monomer and an easily liquefiable gas. The solid particles of growing polymer may be formed in a separate reactor in the presence of the condensed easily liquefiable gas and the polymer seeds having the catalyst adsorbed thereon conveyed by evaporation of the liquefiable gas to the reactor containing the fluidized bed. The olefin may be ethylene or propylene. The liquefiable gases may be propane or butanes. The catalyst may be aluminium triisobutyl and TiCl4, or aluminium monochlorodiethyl, and TiCl3. A flow diagram is given of a continuous process.
