WebIn this case, the cationic polymerization reaction is initiated by adding a strong acid to an alkene to form a carbocation. The ion produced in this reaction adds monomers to produce a growing polymer chain. The chain reaction is terminated when the carbonium ion reacts with water that contaminates the solvent in which the polymerization is run. WebMar 19, 2024 · Synthetic polymers are often used as a coagulant and filter aid but have also been used as a primary coagulant. Operators use different charged groups of polymers known as cationic (positive), anionic (negative), and nonionic (without ionizable groups). Coagulation aids assist in the building of settable floc.
