Abstract

An apparatus for the polymerization of olefin monomers comprising means for forming a fluid stream containing catalyst, means for continuously feeding the fluid stream into an elongated polymerization reactor having at least two successive chambers separated by dividing plates having a diameter slightly smaller than that of the polymerization rector, means for feeding monomers, and an optional catalyst and donor into the polymerization reactor under temperature conditions to polymerize the olefin while maintaining a mixed flow in the chambers to polymerize the monomers and optional comonomer in the fluid, and means for removing the resultant polymer slurry from the polymerization reactor.
