Five cationic polyacrylamides (cPAM) with different molar mass and charge density were used in this study. They all are copolymers of acrylamide and acryloyloxyethyltrimethyl ammonium chloride with a cationic monomer content between 40 and 50%
- What is cationic polyacrylamide (CPAM)?
- Cationic polyacrylamides (CPAMs) are widely utilized due to their excellent performance in flocculation and sludge dewatering [ 2 ]. Numerous studies have been conducted on CPAM synthesis technologies, including grafting, free radical polymerization, and polymer modification [ 3 ].
- 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 .
- What are the different types of polyacrylamide?
- There is a wide range of diverse solution polyacrylamides available in the commercial marketplace (anionic, cationic, and nonionic). They cover a wide range of charges and can range in molecular weights from the thousands to one or two million Daltons.
- 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 ).
