Concentrated, stable water-in-oil emulsions of water-soluble or water-swellable polymers are prepared by polymerization of one or more water-soluble ethylenically unsaturated monomers in a water-in-oil emulsion and removal of water from the water-in-oil polymer emulsion by azeotropic distillation, by a method in which superheated vapor of an inert organic solvent which is immiscible with water is passed into the water-in-oil polymer emulsion. Using the process, it is also possible to concentrate emulsions which tend to coagulate or water-in-oil emulsions which are sensitive to shearing, without the polymers losing their effectiveness.
