- What is cationic polyacrylamide?
- Cationic Polyacrylamide is white power or granule, the degree of ion is from 5% to 80%, soluble, good water solubility, can be dissolved in water at any percentage and be undissolved in organic solvents. CPAM shows characteristics of high polymer electrolyte, suitable for wastewater treatment with a negative charge and rich organic matter.
- What type of polyacrylamide is used in oil industry?
- The polyacrylamide use can be anionic, cationic, or nonionic with various ratios of the comonomers used in the case of the anionic and cationic polymers. The anionic polyacrylamides in the oil field industry are designated by the generic name of partially hydrolyzed polyacrylamide (PHPA), although they are in actuality copolymers .
- Why is anionic polyacrylamide chosen?
- Anionic polyacrylamide is chosen because the intramolecular electrostatic repulsion between polymer segments forces the polymer chains to adopt a more extended conformation, increasing the efficiency of bridging flocculation.
- Which comonomer is used for the production of anionic polyacrylamides?
- The workhorse comonomer for the production of anionic polyacrylamides is acrylate salts of acrylic acid. These anionic polymers can be prepared as various mono- and divalent metal salts and other positively charged inorganic and organic counterions of the polymerization of acrylic acid with acrylamide (see Fig. 34.4 ).
