    Abstract: An additive for deep-well cement slurries comprising a water-soluble anionic copolymer having a molecular weight from about 50,000 to 500,000 and comprising about 1 to 60 mole % of anionic structural units and about 99 to 40 mole % of nonanionic structural units. A preferred additive comprises a terpolymer of acrylamide, sodium acrylate and sodium vinylsulphonate. The additives retard the setting action of the slurry, stabilize the slurry, prevent the swelling of readily hydratable clays and are resistant to electrolytes which would accelerate setting and seepage of water from the slurry.

    Abstract: 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.
