Abstract
Cationic polymers and methods for using the same are provided. The method can include contacting an aqueous medium with a cationic polymer. The cationic polymer can include a polymer formed by reacting an aldehyde, and optionally an aldehyde-reactive compound, in the presence of a sufficient amount of guanidine to provide the polymer with a net cationic charge.
