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 mixture of an aluminum or chromium salt of an alkyl salicylic acid and an alkali metal alkyl sulfosuccinate.
Claims5
In a process in which at least one olefin is polymerized in a hydrocarbon diluent in a turbulent reaction zone to produce particles of polymer which are substantially insoluble in the diluent;
- the method of reducing adherence of polymer particles to the walls of the reaction zone which comprises adding to the reaction medium a composition comprising (1) at least one aluminum or chromium salt of an alkyl salicylic acid and (2) at least one alkali metal alkyl sulfosuccinate.
