Abstract

A batchwise or continuous process for producing coagulated particles of polymer latex, involves partially or completely filling at least one receptacle with a fluid A which can be water, a polymer latex emulsion or a coagulant solution, the receptacle being equipped with baffles containing at least one orifice, injecting into the receptacle at least one fluid other than the fluid of the preceding stage, the injected fluid being a polymer latex emulsion and/or a coagulant solution, and in then creating and maintaining within the receptacle an oscillatory flow or an impulsive flow, in conjunction with the formation of eddies or of vortices.
