Abstract

An improvement in the process for producing sticky polymers in a fluidized bed reactor catalyzed by a transition metal catalyst in the presence of an inert particulate material prone to generate excessive negative charges in said reactor, by conducting the process in the presence of a composition comprising a mixture of an alcohol phosphate salt and a quarternary ammonium salt, which is dissolved in a suitable solvent.
