Polymerization process for the polymerization of monomer in a polymerization system having at least one component attached thereto which component is flushed with a flush medium which enters the polymerization system. Initially, the component is flushed with a first flush medium, and subsequently the component is flushed with a second flush medium.

Polymerisation process

Process for the polymerization of monomer in a polymerization system having at least one component attached thereto which is flushed with a flush medium which enters the polymerization system. Initially, the component is flushed with a first flush medium, and subsequently the component is flushed with a second flush medium which differs in composition from the first flush medium. A flush gas containing monomer is used as the flush medium when the polymer production rate is above 10 Te/h.

Process for controlling the (co)polymerization of olefins in a continuous polymerization reactor wherein the olefin (co)polymerization is performed in an industrial plant reactor in the presence of a polymerization catalyst characterized in that at least one operating parameter of the plant is controlled by means of a measurement of the chain branching level (CBL) of the produced polymer.

Process control for the (co)-polymerisation of olefins

The present invention relates to a process for the gas-phase (co-)polymerization of olefins in a fluidised bed reactor using a late transition metal catalyst characterised in that the polymerization is performed in the presence of a process aid additive.
