Nonionic polyacrylamides are used, among other things, in mining to improve throughput, enhance yield and optimize processes especially where low pH conditions are involved. Nonionic powder flocculants can be produced with very high molecular we
The molecular weight (MW) of commercial PAM ranges from 10 5 to >10 7 Da. High MW PAM (>10 6 Da) has a wider range of applications due to its high viscosity, drag reduction capabilities, and water
Properties of Polyacrylamides
Properties. Polyacylamides are high molecular weight water soluble or swellable polymers formed from acrylamide or its derivatives. Their glass transition temperature is well above room temperature (> 400 K). The only commercially important p

- How cationic polymers are synthesized?
- These cationic polymers are synthesized by free radical polymerization of acrylamide and their derivatives by the copolymerization method, which includes solution, precipitation, and emulsion techniques. The Mannich reaction is another important method by which the cationic polymers can be processed.
- Are cationic and anionic polymers the same?
- Both anionic and cationic polymer forms are known; however, the bulk of commercially successful products are cationic. These products are useful particularly in papermaking applications where the presence of oils and surfactants are environmentally unfriendly or are detrimental to the papermaking process. 34.2.5.3. Dry polyacrylamides
- What is an anionic polyacrylamide?
- Anionic polyacrylamides make up the largest portion of the polyacrylamide market. The polymers can be prepared over a wide range of anionic charges and molecular weights (1000 to > 20,000,000 molecular weight). The workhorse comonomer for the production of anionic polyacrylamides is acrylate salts of acrylic acid.
- How cationic charge is imparted in Mannich reacted polyacrylamide?
- These systems are exclusively solution polymers and the high-molecular-weight Mannich-reacted polyacrylamides can have substitution levels to about 80 mole%. The cationic charge is imparted by lowering the product pH which results in the protonation of the Mannich base.
