Process for production of water-soluble polymer dispersion

摘要

A process for preparing a water-soluble polymer dispersion is here provided which is characterized by polymerizing water-soluble monomers of 5 to 1000 mole % of a cationic monomer represented by formula (I) defined herein, 0 to 50 mole % of another cationic monomer represented by formula (II) defined herein and 0 to 95 mole % of (meth)acrylamide in the presence of 1 to 10% by weight of an organic high-molecular multivalent cation based on the total weight of the monomers in a multivalent anionic salt aqueous solution having a concentration of 15% by weight or more.
