Abstract
Polyalkylene imines containing 2-hydroxypropyltrimethylammonium salt side chains are obtained by reaction between alkylene imine polymers and copolymers and a glycidyltrimethylammonium salt. These polymers are very effective flocculants, particularly in the area of water clarification. They are obtained from a variety of sources, e.g. by modification of either commercial polyethylene imines or polymers derived from oxazolines, and oxazinolines, from the polymerization of aziridine monomers or from the condensation of a low molecular weight polyamine and a dihaloalkane.
