Abstract

Improved process for the polymerization and/or copolymerization in a fluidized bed of ethylenically unsaturated monomers, according to which one works in the presence of one or more catalysts or initiators, of a solid substance and at a pressure lower than the saturating vapor pressure of the or the monomers to be polymerized, and in which the monomer or monomers are injected in liquid form, characterized in that in order to thermally control the polymerization reaction, the monomer or monomers are injected into the fluidized mass with the intervention of at least one jet of liquid monomer whose initial diameter is between 0.1 and 1.5 mm at a height between 0 and 75% of the height of the fluidized mass.
