Abstract: A latex of a rubbery polymer material is produced from a solution of said polymer in an organic solvent by mixing the solution with water, evaporating the solvent, subjecting the obtained foamy product to the shear forces generated in a radial symmetrical space caused by injecting into the space, tangentially to the foam therein, a flow of gas or liquid. The treated foam includes the rubbery polymer, water, an organic solvent and at least one emulsifying agent. When subjected to shear forces, the foam breaks releasing the gaseous organic solvent which is removed from the obtained latex.
