“…Polymers such as polyacrylamide, copolymers of acrylic acid, and their derivatives are known and widely used worldwide. In the synthesis of most polymers, the primary chemical compounds are polyacrylamide, polyacrylonitrile and their derivatives, sodium acrylate, poly vino vinyl alcohol, polyphenolic compounds, polyvinyl pyridine, polyethylene glycols, polyethylene oxide, acrylic acid, methacrylic acid, dialyldimethylammonium chloride, styrenosulfonic acid and vinylsulfonic acid (Anielak 2000, Antonova et al 2005, Bajdur et al 2001, Grachek et al 2001, Novakov et al 2001, Qian et al 2004, Shulevich et al 2005, Bajdur et al 2011. Synthetic polymers, including polyacrylamide or copolymers, are often used as flocculants in wastewater treatment processes.…”
