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.

Abstract: A mixture containing bitumen, a high-boiling hydrocarbon and an EPDM-rubber is prepared by dissolving the EPDM under special conditions in the hydrocarbon and by subsequently mixing the resulting solution with bitumen. An improved bitumen is obtained that can be applied, for instance, in road construction. Preferably during the dissolution of EPDM in hydrocarbon, oxygen is incorporated into the mixture in a forced manner in order to achieve improved dispersion.
