  • Method of clarifying water using low molecular weight cationic dispersion polymers
    Patent number: 6398967
    Abstract: This invention is directed to a method of clarifying water comprising adding to the water an effective clarifying amount of a low molecular weight water-soluble cationic dispersion polymer prepared by polymerizing one or more cationic monomers and one or more nonionic monomers and one or more chain transfer agents under free radical forming conditions in an aqueous solution of an anionic salt in the presence of a stabilizer polymer, wherein the cationic dispersion has a cationic charge of from about 1.0 mole percent to about 75 mole percent and an RSV of from about 0.2 dl/g to about 6 dl/g.
