WO1997007162A1 - Polyacrylamide with low molecular weight
The invention concerns a polyacrylamide-containing composition which is characterized in that it has a molecular weight of between 2,000 and 8,000 g/mol, determined by means of gel permeation chromatography (GPC), and as a 15 wt % aqueous solution still has a Brookefield viscosity of between 100 and 500 mPas at 25 °C. The invention further concerns the use of this polyacrylamide-containing
Introduction to Polyacrylamide Gels. Print. Overview Gradient gels allow resolution of both high- and low-molecular weight bands on the same gel. The larger pore size towards the top of the gel permits resolution of larger molecules, while pore sizes that decrease toward the bottom of the gel restrict excessive separation of small molecules

Polyacrylamide gels are characterized by two parameters: total monomer concentration (%T, in g/100 ml) and weight percentage of crosslinker (%C). By varying these two parameters, the pore size of the gel can be optimized to yield the best separation and resolution for the proteins of interest.

- Can hydrolyzed polyacrylamide be degraded?
- For oil field applications, partially hydrolyzed polyacrylamide (HPAM) is the most widely used polymer. HPAM must maintain high viscosity to achieve good oil recovery. In reality, however, polymers can be severely degraded by shearing and heat in the underground environment. This phenomenon is studied in this paper.
- What is hydrolyzed polyacrylamide (HPAM)?
- Hydrolyzed polyacrylamide (HPAM), a derivative resulting from the hydrolysis of PAM, demonstrates significant thickening capabilities in freshwater and at relatively lower temperatures (<75 °C) due to strong intra- and inter-chain electrostatic repulsion of carboxylate groups 14.
- Is HPAM a water soluble polymer?
- HPAM is a water-soluble, commonly injected polymer into oil reservoirs to improve the water flooding process (Xue et al., 2025; Zhao et al., 2008).
- What is high molecular weight polyacrylamide (PAM)?
- Provided by the Springer Nature SharedIt content-sharing initiative High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.
