ABSTRACT:
The present invention is directed to a method for production of a water-soluble cationic polymer comprising polymerizing a cationic vinyl monomer; either a cationic acrylate monomer alone or a mixture of said monomer and another monomer copolymerizable therewith, in dispersion medium in the presence of a surfactant by suspension polymerization method. The present invention offers an industrially advantageous method to obtain the water-soluble cationic polymer with a high degree of cationization and a high viscosity in water solution which can be used for flocculants, antistatic agents, retention aids for paper manufacturing and other purposes.
