ABSTRACT:
An olefin or mixture of olefins is polymerized in a hydrocarbon diluent in a turbulent reaction zone to produce particles of polymer which are substantially insoluble in the diluent (particle form process). 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 mixture of (a) a polysulfone copolymer, (b) a polymeric polyamine, and (c) an oil-soluble sulfonic acid.
