Abstract
Method for switching between steady-state and non-steady-state operations of a process for the production of a polymer by polymerization of a monomer in the presence of a comonomer and/or hydrogen. The process includes (a1) at non-steady-state controlling the process based on the ratio of comonomer to monomer in the reactor, and (b1) at steady-state controlling the process based on the flow ratio of comonomer to monomer to the reactor, and/or (a2) at non-steady-state controlling the process based on the ratio of hydrogen to monomer in the reactor, and (b2) at steady-state controlling the process based on the flow ratio of hydrogen to monomer to the reactor.
