1. the method for olefin polymerization comprises:

  • A) at least a liquid olefin monomer of polymerization in polymerization reactor comprises the polymerisation slurry of polyolefine and described liquid monomer with formation;

    B) utilization comprises that the line of pipes of pipeline is transported to flashing chamber with polymerisation slurry continuously from polymerization reactor, forms the turbulent flow that comprises the monomeric three-phase logistics of polymkeric substance, liquid monomer and gaseous state in described pipeline;

    C) in described flashing chamber, from polymkeric substance, separate the monomer that evaporates;

    The stain control agent that the method is characterized in that liquid form is by introduction step b continuously) described in the inlet upstream of pipeline.
