1. control the method for continuous fluid bed bioreactor (being total to) polymerization process, it comprises:

  • (i) take out the thermal cycling logistics that contains principal monomer and another kind of at least unreacted reactant by reactor,(ii) cooling segment or all by the described recycle stream that takes out in the described reactor and(iii) in the presence of polymerizing catalyst, under reaction conditions, make the logistics of refrigeration cycle that partly or entirely contains principal monomer and unreacted reactant cycle through the zone of convergency of described reactor,It is characterized in that described control method comprises the density span of controlling polymers powder particle.
