Abstract
A cationic latex terpolymer prepared by polymerizing from about 1 to about 99.1 mole percent of one or more cationic monomers, from about 0.9 to about 5 mole percent of one or more hydroxyalkyl (meth)acrylates and from 0 to about 98.1 mole percent of one or more nonionic monomers is useful for dewatering sludge.
