Abstract:
A process for polymerization of olefin monomer and optionally other monomer in the presence of olefin polymerizing catalyst, diluent and optional cocatalyst and donors, said process comprising the steps:forming a fluid stream containing said catalyst,continuously feeding said fluid stream into an elongated polymerization reactor (1) comprising at least two successive chambers (12a) separated by dividing plates (12b) having a diameter slightly smaller than that of the polymerization reactor (1) thereby defining a space between a peripheral edge of said dividing plates (12b) and a wall of said reactor1,feeding into said polymerization reactor (1) monomer and optionally co-catalyst and donor under temperature conditions to polymerize said olefin monomer while maintaining a mixed flow in said chambers (12a) to polymerize the monomer and optional comonomer in the fluid, andremoving the resulting polymer slurry from said polymerization reactor.
