ABSTRACT OF THE DISCLOSURE A water-in-oil polymer emulsion having an excellent fluidity can be obtained by a process which comprises dispersing an aqueous solution of at least one monomer comprising (meth) acrylic monomer having a quaternary ammonium salt or a tertiary amine salt and a hydrophobic organic liquid in the presence of an oil-in-water type nonionic surfactant, and heating the resulting dispersion to a temperature of at least 40°C to polymerize. These emulsions are useful as flocculants, particularly in separating finely divided solids from aqueous suspensions.
