  • How is an anionic polyacrylamide flocculant synthesized?
  • In this study, an anionic polyacrylamide flocculant was synthesized by ultrasonic initiated template copolymerization (USTP), using sodium allylsulfonate (SAS) and acrylamide (AM) as monomers, poly diallyl dimethyl ammonium chloride (polyDADMAC) as template, and 2,2′-azobis [2- (2-imidazolin-2-yl) propane] dihydrochloride (VA-044) as initiator.
  • Is Apam-t a novel anionic polyacrylamide?
  • APAM-T is a novel anionic polyacrylamide which has been successfully synthesized by ultrasonic initiated template copolymerization. Characterization results showed the evidence of the microblock structure’s existence and the enhancement of copolymerization degree by adding the template.
  • 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.
  • Can UV-initiated template polymerization prepare a novel anionic polyacrylamide with a microblock structure?
  • E-mail: zhl6512@126.com; Fax: +86 23 65120827; Tel: +86 23 65120827 Ultraviolet (UV)-initiated template polymerization (UTP) was used as a feasible strategy to prepare a novel anionic polyacrylamide (APAM) with a microblock structure.
