PCT No. PCT/EP86/00362 Sec. 371 Date Feb. 13, 1987 Sec. 102(e) Date Feb. 13, 1987 PCT Filed Jun. 19, 1986 PCT Pub. No. WO86/07596 PCT Pub. Date Dec. 31, 1986.The present invention relates to a process for the production of concentrated, water-soluble or water swellable emulsion polymers by the polymerization of at least one water-soluble monomer in a water-in-oil dispersion by means of polymerization initiators, preferably in presence of bi- or multi-function vinyl- or allyl compounds in which a water-in-oil dispersion of the starting monomers is polymerized while being stirred so that the heat of polymeriaation is eliminated by distillation removal of the water contained in the reaction mixture. The polymerisation temperature is preferably adjusted and controlled by means of the pressure in the system.
