Synthesis and application of nonionic polyacrylamide with controlled molecular weight for fracturing in low permeability oil reservoirs, Journal
Nonionic polyacrylamide (NPAM) with controlled molecular weight was successfully synthesized as a gel fracturing fluid by aqueous solution polymerization. The effects of the monomer concentration, initiator concentration, reaction time, feeding
known that the gelling solution prepared with high molecular weight PAM possesses high initial viscosity. This would make it di cult on the injection process for water shuto treatment. Fortunately, gel systems prepared with nonionic polyacrylami

Polyacrylamide (PAM) is a linear organic polymer, and it is the most widely used flocculant in water treatment chemicals.It can enhance flocculation, reduce the cost of clean water, improve water quality, and remove organic matter and algae in
Synthesis and Characterization of Acrylamide-Based Anionic Copolymer and Investigation of Solution Properties - Hindawi
The copolymer of acrylamide (AM) and 2-acrylamido-2-methyl-1-propane sulfonic acid (AMPS) was synthesized through radical solution polymerization by potassium persulfate as initiator. By changing the AMPS feed ratio from 10 to 70%, and keeping
Nonionic polyethylene oxide (PEO) and anionic polyacrylamide (PAM) flocculation of kaolinite dispersions has been investigated at pH 7.5 in the temperature range 20-60 degrees C. The surface chemistry (zeta potential), particle interactions
Introduction to Polyacrylamide Gels | LSR | Bio-Rad
The practical ranges for monomer concentration are stock solutions of 30-40%, with different ratios of acrylamide monomer to crosslinker. The designations 19:1, 29:1 or 37.5:1 on acrylamide/bis solutions represent crosslink ratios 5%, 3.3% and
The adsorption of nonionic polyacrylamide on sodium nontomorillonite is studied using different molecular weight macromolecules (mol wt = 4.40 × 10 4, 1.20 × 10 5, 3.70 × 10 5, 3 × 10 6), with the monomeric unit represented by the isobutyramide
