Abstract:
An apparatus for polymerization of olefin monomer and optionally other monomer in the presence of olefin polymerizing catalyst, diluent and optional cocatalyst and donors, said apparatus comprising:means for continuously feeding a fluid stream containing said catalyst into an elongated polymerization reactor (1) having at least two successive chambers (12a) separated by dividing plates (12b) having a diameter slightly smaller than that of the polymerization reactor (1), wherein said dividing plates (12b) have a diameter decreasing towards the end of the reactor; means for feeding into said polymerization reactor (1) monomer and optionally cocatalyst and donor under temperature conditions to polymerize said olefin while maintaining a mixed flow in said chambers (12a) to polymerize the monomer and optional comonomer in the fluid, and means for removing the resulting polymer slurry from said polymerization reactor.
