  • How is cationic polyacrylamide produced?
  • Cationic polyacrylamides can be produced via copolymerization with a cationically charged vinyl monomer or by postreaction of the homopolymer of acrylamide with cationizing species. Of the two, the copolymerization route is the most widely used across all product forms.
  • 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.
  • How is ionic polyacrylamide prepared?
  • Anionic polyacrylamide can also be prepared by the hydrolysis of nonionic polyacrylamide ( Fig. 34.7 ). The process generally involves the addition of a strong base to a homopolymer of polyacrylamide. This can be done in an aqueous solution, inverse emulsion. Recently, a process to produce dry forms of hydrolyzed polyacrylamide has been developed.
  • How cationic polymers can be processed?
  • The Mannich reaction is another important method by which the cationic polymers can be processed. In this review paper, the preparation methods, interaction mechanisms of these polymers, and their popular industrial applications are summarized.
