Anionic and cationic polyacrylamide are two types of polyacrylamide polymers with different charge properties. Here are the main differences between them: 1. Charge properties: The key distinction lies in their charge characteristics. Anionic polyacrylamide has a negative charge due to the presence of anionic groups (such as carboxylate or sulfate groups), while cationic polyacrylamide has a ...

Get PriceWhat is polyacrylamide (PAM)?
This chapter discusses polyacrylamides (PAM). Among the various polymers that have been studied for chemical enhanced oil recovery, PAM is most important. PAM is used frequently for mobility control as well as permeability control. PAM (and its modified forms) is the principal polymer used in significant amounts on a commercial basis.
What are the adsorption properties of Pam polymers?
The polymer’s adsorption properties in dependence on the following parameters solution pH (in the range 3–9), temperature (in the range 15–35 °C), and carboxyl groups’ content in the PAM chains (in the range 5–30 %) were examined. The turbidimetry method was applied for determination of the suspension stability of alumina in the presence of PAM.
Do polyacrylamide-type polymers have good thermal stability?
Polyacrylamide-type polymers with good thermal stability present good long-term stability at high temperature and high salinity conditions. Viscosity reduction of polyacrylamide-type polymers with good thermal stability was owing to polymer main chain degradation at harsh conditions.
What type of polymer is Pam?
PAM (and its modified forms) is the principal polymer used in significant amounts on a commercial basis. Usually, anionic versions of PAM are used rather than the nonionic homopolymer itself. By far, poly (acrylamide- co -acrylic acid) is the most common, and the nomenclature PAM/AA is used in this chapter to refer to this group of polymers.
Why is Pam/AA a good polymer?
Thus, the end result is a reduction in the permeability to the displacement fluid. According to equation (8-1) this serves to improve the mobility ratio. The retention property is distinctive of PAM/AA. It represents an advantage of PAM/AA over the other major EOR polymer, i.e., xanthan gum.
What type of polyacrylamide is Apam?
Amphoteric Polyacrylamide. APAM is formed by hydrolysis and copolymerization of vinyl amide and vinyl cationic monomer acrylamide monomer. It is an irregular zwitterionic polymer with both positive and negative charges on the molecular chain. Non-ionic Polyacrylamide.
