Graft polymers produced by the reaction of starch with cationic, anionic and nonionic acrylic monomers show considerable potential as flocculating agents for treatment of industrial and municipal wastewaters, for beneficiation of mineral ores and for retention of clay in filled paper. Performance of the polymers depends on the nature of the system being treated and on the structure of the starch grafts. Percent add‐on, grafting frequency, molecular weight of grafted chains and ionic charge are important variables in starch graft polymer structure that influence performance. Effectiveness of the polymers as flocculants has been demonstrated in laboratory tests and in on‐site trials. Methods of preparation have been developed and the various polymers characterized.
