METHOD FOR CONTROLLING A PROCESS FOR POLYMERISATION OF AN OLEFIN

摘要

The present invention relates to a method for controlling a process for polymerisation of an olefin, and in particular to a method for controlling a process for polymerising at least one olefin in a reaction zone, said process comprising in the reaction zone a reaction mixture and polymer particles, the reaction mixture comprising a principal olefin and at least one further reagent, and wherein the process is controlled using a parameter indicative of the ratio of at least one further reagent to principal olefin in the amorphous phase of the polymer particles in the reaction zone.
