ABSTRACT:
A water-soluble cationic (co)polymer dispersion prepared by the polymerization of a specified cationic quaternary monomer, which is obtained by quaternization by use of an alkyl halide, optionally with another cationic monomer and/or (meth)acrylamide, the polymerization being carried out in a salt solution which does not dissolve the resulting (co)polymer, and in the presence of a specific cationic polymer dispersant which is soluble in the salt solution, and its use as a flocculant or a paper chemical are provided.
