Polyacrylamide

From Wikipedia, the free encyclopedia Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries. [1]

Effects of polyacrylamide molecular weight and mass concentration on

Comparing the saturated hydraulic conductivity of treatments with different molecular weights under the same PAM mass concentration, it was found that the effect of molecular weight on saturated hydraulic conductivity differed between high PAM mass concentrations (0.08% and 0.16%) and low PAM mass concentrations (0.01% and 0.04%).

Polyacrylamide [IUPAC poly(2-propenamide), hereafter PAM] is a polymer (¨CCH 2 CHCONH 2 ¨C) formed from acrylamide subunits. Polyacrylamide with only acrylamide monomers is nonionic; other monomers such as acrylate or 2-acrylamido-2-methylpropane sulfonate (AMPS) can be copolymerized at various percentages to form anionic PAM.

The effect of polyacrylamide molecular weight, 10 4 and 10 6 , and concentration, 3¨C53 mg mL ?1, on adsorption to gold and silver plates was investigated using QCM-D. 180 A lower amount of higher molecular weight polymers was required to form a thick layer than lower molecular weight polymers, as seen in Figure 27. This information can further be used to determine interactions of polymer

Plots relating gel mobility (R f) to the logarithm of molecular weight (M r) confirmed that the SDS/PAGE mobility of TM-mimetics relative to reference proteins was reduced at smaller M r s, equivalent at an M r corresponding to the intersection point of the two curves, and increased as M r s exceeded the intersection point (Fig. S3 and Table S1).

Optimizing the Conditions of Cationic Polyacrylamide Inverse Emulsion

Based on the response surface methodology in Figure 10 a,b,e,f, when the reaction temperature increased from 55 ¡ãC to 60 ¡ãC, the molecular weight of polyacrylamide cations increased rapidly, and reached its maximum at 60¨C62 ¡ãC. When the temperature continued to increase to 65 ¡ãC, the molecular weight of the polymer tended to decrease.
