A fluidized bed olefin polymerization process incorporates a recycle of a vent gas, containing unreacted monomers, from the product purge bin vessel to the polymerization reactor. The recycle of the vent gas minimizes the loss of the unpolymerized reactants, thereby decreasing overall process and product costs.
