ABSTRACT:
An olefin is polymerized in a hydrocarbon diluent in a turbulent reaction zone to produce particles of polymer which are substantially insoluble in the diluent. Fouling of the reactor by adherence of polymer particles to the walls of the reactor is reduced by adding to the reaction medium a composition which comprises a porphyrin compound, alone or together with a metal alkyl sulfosuccinate. This composition is also useful as an antistatic agent for liquid hydrocarbons and halohydrocarbons.
