amphoteric polymer flocculant amphoteric polymer

Polymer Flocculants | SpringerLink

Amphoteric polyacrylamide is copolymerized by acrylic cationic monomer and acrylamide monomer. The anionic charge forms after the hydratization of the acrylamide monomer, and the cationic charge forms from the acrylic monomer. Thus, the amphoteric polyacrylamide has both positive and negative charges on its molecular chain.

Water Soluble Polymer Flocculants: Synthesis

There is no universally accepted formal definition for flocculation, but it is generally accepted that flocculation is the aggregation of solids achieved with the help of high molecular weight polymers through the formation of bridges between particles.

Representative amphoteric polymer ?occulants are composed of methacryloxyethyl trimethy-lammonium chloride, acryloyloxyethyl trimethylammonium chloride, acrylamide, and acrylic acid. Amphoteric polymer ?occulants have molecular weight of several million to less than 20 million and have cationic parts and anionic parts in the same polymer chain.
