Polyacrylamide degradation and its implications
The hydrolyzed form of polyacrylamide (HPAM), a co-polymer of acrylamide and acrylic acid, is the most widely used anionic PAM in oil and gas development as well as in soil conditioning. 1,9,12,21
Cationic polyacrylamide can be produced in reactions of the amide groups with formaldehyde and a secondary amine, with so-called Mannich bases as the products. Charged polyacrylamides can also be synthesized by copolymerization of acrylate with acrylamide, or with amino-derivatives of acrylate or methacrylic acid esters to obtain anionic and
Quantitative characterization of polyacrylamide–shale
In cationic polyacrylamide (with no salts), there was not a significant difference in zeta potential values for the shales, whereas in the presence of salts (KCl and NaCl) or TMAC (Fig. 5), Chattanooga shale had higher zeta potential values which is indicative of higher polyacrylamide adsorption density than Pride Mountain shale.
This research work discusses the feasibility of polyacrylamide-grafted-polyethylene glycol/SiO 2 nanocomposite as a potential additive for the drilling of troublesome shale formations which may lead to severe wellbore instability problems. The free radical polymerization technique was adopted for the synthesis of the nanocomposite and it was characterized by Fourier transform infrared

Cationic polyacrylamide is projected to be the fastest-growing segment during the forecast period, due to the increasing usage of cationic polyacrylamide in various applications in diverse industries, such as additives in building & construction, color removal and desalination in wastewater treatment, and cell separation in biotechnological broths.
- What is the difference between agarose gel and polyacrylamide gel electrophoresis?
- In polyacrylamide gel electrophoresis, polyacrylamide gel separates macromolecules, i.e., proteins of size five kDa to 250 kDa. Similarly, it can also isolate DNA of 5- 500 bp size. In agarose gel electrophoresis, agarose gel separates DNA, RNA, and protein. It can isolate DNA about 50-20,000 bp in size.
- What is the pore size of polyacrylamide gel electrophoresis?
- Polyacrylamide gel electrophoresis (PAGE) provided uniform pore size for separation of proteins ranging in size from 5 to 2000 kDa. Pore size of gel is controlled by concentrations of acrylamide and bis-acrylamide used in preparation of gel . There are two types of gels used, namely, stacking gel and separating/resolving gel.
- What is polyacrylamide gel electrophoresis?
- The most commonly used polyacrylamide gel electrophoresis for quantitative protein analysis is Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). The polyacrylamide gel forms by polymerizing acrylamide and a crosslinking agent, i.e., N, N’-methylene-bis-acrylamide.
- Why is polyacrylamide better than agarose?
- The pores formed in polyacrylamide are smaller than those of agarose, used for agarose gel electrophoresis. This makes it more suitable for the separation of proteins over large polynucleotide DNA or RNA fragments and allows the separation of relatively small proteins.
