    1. Industrial water treatment Amphoteric polyacrylamide has been widely used for industrial water treatment, oil refinery plants and mining etc. Amphoteric polyacrylamide has a better performance and efficiency than the mono-ionic polyacrylamide, especially when the water condition is complicated, or the water condition is keep changing, because its ability to decrease the surface tension of

    Molecular Weight of Amphoteric Polyacrylamide: How it is

    Amphoteric polyacrylamide (AmPAM) is a linear water-soluble polymer that has been applied in papermaking as an agent for flocculation, retention, filtration, and dry-strength improvement. However, AmPAM with different ranges of molecular weight (MW) have different properties in these processes.

    3, lowering resistance: PAM can effectively reduce fluid friction, the water can be added to trace PAM 50-80% reduction in resistance. 4, thickening: PAM have a thickening effect under neutral and acid conditions, when the PH value above 10 PAM easy hydrolysis. When semi-mesh structure, thickening more obvious. PAM usage instructions

    Preparation and properties of amphoteric polyacrylamide

    Amphoteric polyacrylamide (AmPAM) was prepared successfully through seeded dispersion polymerization with acrylamide, methacrylatoethyl trimethyl ammonium chloride and acrylic acid as comonomers in ammonium sulfate solution. It was characterized by 1 H nuclear magnetic resonance (1 H NMR) and elemental analysis. The particle morphology and

    Super high molecular weight copolymers of AM/NaA/AMPS were prepared by oxidation–reduction [OR-P(AM/NaA/AMPS)] and controlled radical polymerization [CR-P(AM/NaA/AMPS)]. The resulting copolymers were fully characterized, and the reaction conditions for their preparation were optimized.

    When the molecular weight exceeds 1 × 10 7 g/mol, the DR rate reaches the maximum at a concentration of 200 mg/L; with a molecular weight of 5 × 10 6 g/mol, the maximum DR rate is obtained at a concentration of 600 mg/L. Given high molecular weight, HAWSP has a long backbone chain, which is beneficial for absorption and release of energy
