Abstract:
The invention relates to a reactor system for the catalytic polymerization of olefin monomer and optionally comonomer (s), comprising one or more inlets for olefin monomer, catalyst, optionally for comonomer, chain growth controllers or chain transfer agents, and/or inert gas, an outlet for gas and an outlet for polymerization particles, which reactor system comprises at least one fluidized bed unit and at least one a moving bed unit, wherein the fluidized bed unit comprises means for maintaining a fluidized bed in the fluidized bed unit and wherein the moving bed unit is provided with an inlet and an outlet which are connected to the fluidized bed unit, wherein in the fluidized bed unit is positioned shielding means such that via the outlet of the moving bed unit inflow of fluidization gas is inhibited and outflow of polymerization particles allowed and to a process and use thereof.
