Abstract
A continuous gas fluidized bed process is disclosed for the production of polymer from monomer wherein a gaseous stream comprising monomer is passed through a fluidized bed in a reaction zone in the presence of catalyst under reactive conditions, withdrawing from the reaction zone polymeric product and a stream comprising unreacted gases and solid particles, cooling the stream and recycling the cooled stream to the reaction zone together with sufficient additional monomer to replace monomer polymerized and withdrawn as polymer product, and wherein at least a part of the recycle stream is cooled to condense a portion thereof and form a liquid-containing mixture wherein the weight ratio of liquid to solid particles is not less than about two to one, and introducing the mixture into the reaction zone wherein the liquid in the mixture is vaporized.
