Water Soluble Polymer Flocculants: Synthesis, Characterization, and

The reduction in the negative zeta potential was found to be considerably greater in the presence of cationic polyacrylamide than anionic and amphoteric polyacrylamide, due to an increased adsorbed layer thickness of cationic polyacrylamide. 208 Amphoteric polymers exhibit both cationic and anionic behaviors, and their strength and a relative number of sites vary depending on surface charge

ANIONIC POLYACRYLAMIDE

NICNAS has assessed anionic polyacrylamide in an IMAP Tier 1 assessment and considers it a polymer of low concern1. In addition, based on an assessment of environmental hazards, NICNAS also identified anionic polyacrylamide as a chemical of low concern to the environment (NICNAS, 2017). Chemicals of low concern are unlikely to have adverse

In-situ rheology and mechanical degradation of EOR polyacrylamide

The chemical crosslinking is usually strong and stable, which has a wide range of applications in oil displacement agents. However, the mechanical degradation occurs at high flow rates, long flow distances, handling equipment, and perforations [21], which results in irreversible and unrecoverable damage to the network, resulting in a rapid viscosity loss [22,23].

Fabricating an anionic polyacrylamide (APAM) with an anionic block

Considering all aforementioned factors, this study attempts to (1) synthesize the template copolymer (TPAS) with the anionic microblock structure through UTP using AM and SAS as monomers, and PAAC as template; (2) elaborate the template polymerization mechanism through the analysis of the association constant KM; (3) characterize the chemical st...

The Improvement of Dry Strength by Synthetic Polymers

Anionic groups can, however, be formed on the polyacrylamide by introducing sodium acrylate or acrylic acid to the monomer solution to form a copolymer. The quantity of sodium acrylate will define just how anionic the polymer becomes. Typical substitution levels are in the range of 5¨C10 mole%, although higher levels are possible.
