摘要: High molecular weight, water-soluble, cross-linked cationic polymers are prepared by reacting amine-functionalized cationic base polymers, in which the monomer units of the base polymer contain from about 0.05 to about 5.0% amine functionalized monomer units and from about 95 to about 99.95% additional monomer units, including cationic monomer units and optional non-cationic monomer units, with an amount of a cross-linking agent, reactive with the amines of the base polymer, providing between about 0.02 to about 3.0 equivalents of cross-linking agent reactive groups per each mole of amine. The polymers are useful as coagulants and as coatings.
