  • 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.
  • Can nonionic polyacrylamide be used as a gel fracturing fluid?
  • Nonionic polyacrylamide (NPAM) with controlled molecular weight was successfully synthesized as a gel fracturing fluid by aqueous solution polymerization.
  • How is polyacrylamide a hydrolyzed polymer?
  • 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. This allows for the preparation of very high-molecular-weight anionic polymers.
  • What is the composition of polyacrylamide gels?
  • The composition of polyacrylamide gels is generally expressed in terms of T (the total acrylamide and Bis monomer concentration in g/100 ml) and C (the percentage of cross-linker in the total amount of acrylamide).
