CONTROL OF SOLUTION CATALYST DROPLETS

摘要

A process, carried out in the gas phase, comprising contacting one or more olefins with a catalyst system containing a carrier gas and a mixture of solids comprising a transition metal compound or complex and a liquid organi c solvent, under polymerization conditions, in a fluidized bed reactor containing resin particles in a fluidized state with the provisos that (a) t he mixture of solids and solvent contains at least 95 percent by weight solids and (b) the mixture is sprayed with the carrier gas into a particle-lean zon e, or the fluidized bed, of the reactor.
