controlled polymerization of acrylamide via one-pot and one
copper-catalyzed controlled polymerization of acrylamide has always been a challenge, which typically exhibits low monomer conversion and broad molecular weight distribution (mwd) or requires complex/multistep reaction procedures, due to the highly active nature of the am radical and its side reactions. to overcome the above challenges, herein, we report the successful synthesis of well

synthesis and characterization of acrylamide‐based anionic
the copolymer of acrylamide and 2-acrylamido-2-methyl-1-propane sulfonic acid (amps) was synthesized through radical solution polymerization by potassium persulfate as initiator. by changing the amps feed ratio from 10 to 70%, and keeping other reaction conditions constant, different copolymers were synthesized.

- What factors affect the flocculation effect of cationic polyacrylamide (CPAM)?
- Cationic polyacrylamide (CPAM) is a commonly used flocculant for water treatment. Factors that affect the flocculation effect and can be controlled manually include the type and dosage of CPAM, wastewater pH, stirring time and settling time, and their reasonable setting is critical to the flocculation effect of CPAM.
- What is cationic polyacrylamide (CPAM)?
- Cationic polyacrylamide (CPAM) is one of the most frequently used flocculants with high intrinsic viscosity and charge density. This flocculant is a water-soluble acrylamide-based polymer having cationic quaternary ammonium groups .
- Is cationic Pam effective in flocculation?
- The success of anionic and cationic PAM in flocculation can be related to particle charges that allow for particle flocculation with polymers. Non-ionic PAM was shown to be ineffective at flocculating tailing particles. The ionicity of the polymer appears to be highly relevant here, based on the results.
- Is acrylamide a cationic flocculant?
- The copolymer of acrylamide (AM) and DMC is used as an effective cationic flocculant in wastewater treatment. A series of copolymers of AM and DMC (PAMC) were synthesized using different approaches. In earlier studies, γ-ray irradiation with inverse emulsion polymerization was employed to copolymerize AM and DMC .
