26,805 PREVENTION OF FOULING IN POLYMERIZATION REACTORS Abstract of the Disclosure An olefin or mixture of olefins is polymerized in a hydrocarbon dilu- ent in a turbulent reaction zone to produce particles of polymer which are sub- stantially insoluble in the diluent (particle form process). Fouling of the reactor by adherence of polymer particles to the walls of the reactor is reducedby adding to the reaction medium a composition which comprises a mixture of (a) a polysulfone copolymer, (b) a polymeric polyamine, and (c) an oil-soulble sul- fonic acid.
