polyacrylamide pam polymer acid to oilfield fracture
Polyacrylamide (PAM) is a high molecular polymer, which has good solubility in water, and good flocculability. It can reduce the friction between fluids. According to the ion properties, polyacrylamide could be characterized as 4 types—anionic PAM (APAM), cationic PAM (CPAM), nonionic PAM (NPAM), and amphoteric PAM (ACPAM).

- Does pH affect water uptake of poly(Aam)-co-poly (AAC) hydrogels?
- Figure 8. Influence of pH on the water uptake of the poly (AAm)-co-poly (AAc) hydrogels. From the plot, it was obviously observed a gradual increase in swelling ratios from pH 2.2–7.0, and then a sharp transition is observed from pH 7.0–10.0 with a slight decrease in water uptake.
- How is free radical copolymerization of PAAM hydrogels carried out?
- After nitrogen bubbling for 15 min, free radical copolymerization of hydrogels was carried in glass tubes of 10 mm inner diameter at room temperature for 2 h, using APS and TEMED as redox initiator. Subsequently, the crosslinking of PAAm hydrogels was carried out by BIS.
- What is a hydrogel synthesis based on poly(acrylic acid) and copolymers?
- The present work focuses on the hydrogel synthesis of poly (acrylamide) and copolymers based on poly (acrylic acid) at various concentrations, N, N ′-methylene bisacrylamide was used as crosslinker. The swelling properties of the hydrogels, in different solutions (water, NaCl) and different pH were systematically studied.
- Which polymer is used as a rheological thickener?
- Poly (acrylic acid), was chosen as a thickener to study the rheological behavior of copolymer hydrogels, PAAc polymers as an anionic hydrogel are widely used to improve the rheological properties of thickening systems.
