  • What is cationic polyacrylamide (CPAM)?
  • Cationic polyacrylamides (CPAMs) are widely utilized due to their excellent performance in flocculation and sludge dewatering [ 2 ]. Numerous studies have been conducted on CPAM synthesis technologies, including grafting, free radical polymerization, and polymer modification [ 3 ].
  • 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 .
  • Which cationic flocculants are synthesized by UV-induced free-radical polymerization?
  • Synthesis of cationic flocculants Poly [2- (acryloyloxy)ethyl]trimethylammonium chloride (PAETAC) and poly (3-acrylamidopropyl)trimethylammonium chloride (PAmPTAC) was synthesized by UV-induced free-radical polymerization in an aqueous solution ( [M] = 1.2 M).
  • What is ionic polyacrylamide?
  • The ionic forms of polyacrylamide has found an important role in the potable water treatment industry. Trivalent metal salts, like ferric chloride and aluminum chloride, are bridged by the long polymer chains of polyacrylamide. This results in significant enhancement of the flocculation rate.
