- 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 .
- How does polyacrylamide biodegradation affect the fate of related polyacrylic acid?
- Polyacrylamide copolymers, either anionic or cationic, are potentially quickly converted to corresponding polyacrylate salts by deamination or hydrolysis. Therefore, biodegradation of related polyacrylic acid (or related salts) provides insights in polyacrylamide biodegradation and their fate.
- Is polyacrylamide a cationic or nonionic polymer?
- Degradable or bioaccumulative. Anionic polyacrylamide has low acute toxicity. Co-chemical properties Polyacrylamide polymers can exist in cationic, anionic or nonionic forms, depending on their ionic charge. Nonionic forms of polyacrylamide are generated from basic polymers.
- Which comonomer is used for the production of anionic polyacrylamides?
- The workhorse comonomer for the production of anionic polyacrylamides is acrylate salts of acrylic acid. These anionic polymers can be prepared as various mono- and divalent metal salts and other positively charged inorganic and organic counterions of the polymerization of acrylic acid with acrylamide (see Fig. 34.4 ).
