Synthesis of High Molecular Weight Cationic Polyacrylamide
Cationic polyacrylamide is a derivative of polyacrylamide, a cationic polymer flocculant which has an excellent effect on sewage treatment. Our existing cationic polyacrylamide are mostly prepared by the Mannich reaction ,which has the shortcomings of more unreacted material, low cationic degree, poor stability, short validity, etc. Therefore, a cationic polyacrylamide has been prepared by
Polyacrylamide (PAM, Mw 10,000) is a low molecular weight nonionic water-soluble polymer used as an additive in CMP slurries, various printing applicatons, and as a flocculant in water treatment. 50% solution in water (packaging size denotes weight of solution).
High Molecular Weight Polymer Anionic Polyacrylamide, High

Among various solvents, mixtures of water–tert‐butyl alcohol and water–acetone were found to be suitable for the synthesis of the high molecular weight polyacrylamide. For polymerization in acetone–water mixtures, the molecular weight of polymer increases with monomer concentration; but at the high concentration, intermolecular

High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction
SELECTIVE USE OF HIGH MOLECULAR WEIGHT POLYACRYAMIDE
The flocculation ability depends on many factors, including the nature and concentration of the polymer, molecular weight, chemical composition and hydrodynamic macromolecular size, concentration of the disperse phase and composition of the dispersion environment. In most cases considered agents have a higher efficiency than the original
General description Rainbow ™ Molecular Weight Markers have been enhanced to enable faster and simpler identification of proteins on SDS-polyacrylamide gels. The ready-to-load markers provide sharper, more intense bands on gels and blots and have improved band spacing for more accurate molecular weight determination.

Detailed Images Polyacrylamide (PAM) is a kind of linear organic high polymer, is also a kind of high polymer flocculant in water treatment products, can absorb the suspended particles in the water, link bridge role between the particles, the fine grain to form bigger floccules, and increasing the speed of the precipitation.
SYNTHESIS AND CHARACTERIZATION OF POLYACRYLAMIDE
The measurement results for intrinsic viscosities of PAAN indicate that the molecular weights of polymers are low and the breakage of the polymer chains can not occur at high shear rate. The

- Can microblocked polyacrylamide improve municipal sludge dewaterability?
- Zhou, Y. et al. Enhanced municipal sludge dewaterability using an amphiphilic microblocked cationic polyacrylamide synthesized through ultrasonic-initiation: Copolymerization and flocculation mechanisms. Colloids Surf. A Physicochem. Eng. Asp. 594, 124645 (2025).
- Are cationic copolymers used in sludge dewatering?
- Four groups of synthesis technologies of cationic copolymers were reviewed, including aqueous solution polymerization, dispersion polymerization, inverse emulsion polymerization and photo initiated polymerization. Furthermore, the paper reviewed that the application of cationic flocculants in sludge dewatering treatment.
- How CPAM is used in sludge dewatering?
- It is very significant and valuable to apply CPAM in the field of sludge dewatering and improve the sludge dewatering and conditioning effect. CPAM is mainly prepared by polymerization of AM and cationic monomer. Acryloxy trimethylammonium chloride (DAC) is one of the more commonly used cationic monomers.
