Abstract:
A process for producing polymer by the reaction of one or more monomers in a fluidized bed reaction vessel having a polymerization zone containing a bed of growing polymer particles which comprises:a) continuously or intermittently introducing the one or more monomers into said polymerization zone;b) continuously or intermittently introducing at least one polymerization catalyst into said polymerization zone;c) providing at least one liquid component in the polymerization zone, said liquid component capable of being in the liquid phase in the polymerization zone in an amount sufficient to substantially eliminate the generation of static in the polymerization zone;d) continuously or intermittently withdrawing polymer product from said polymerization zone;e) continuously withdrawing gases from the polymerization zone, compressing and cooling said gases for recycle to the polymerization zone; andf) continuously maintaining sufficient gas flow through the polymerization zone to maintain the bed fluidized, said gas flow comprising recycle of gases withdrawn from the polymerization zone.
