  • What are the different types of anionic polyacrylamide synthesis technologies?
  • The paper lists six different kinds of anionic polyacrylamide synthesis technologies, including homopolymerization posthydrolysis process, homopolymerization cohydrolysis process, copolymerization approach, inverse emulsion polymerization, precipitation polymerization and radiation polymerization.
  • What is an anionic polyacrylamide?
  • 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 . Both high- and low-molecular-weight polymers are used as drilling fluid additives.
  • What is a high-molecular-weight nonionic polyacrylamide?
  • High-molecular-weight nonionic polyacrylamides are routinely used in the mineral processing industries as thickeners and flocculants [36–38]. The product types for polyacrylamides are solutions, liquids (emulsion or dispersion), and dry powders. The forms each have their own set of advantages and disadvantages as will be discussed in the following.
  • Can anionic polyacrylamide be used in water treatment?
  • What's more, the authors discussed the application status of anionic polyacrylamide in water treatment. Based on these reviews, future research perspectives relating to its synthesis and application were proposed. This review summarizes the synthesis methods for anionic polyacrylamide.
