The scaling exponents of polyacrylamide and acrylamide
The ratio of bulk modulus to shear modulus, Ke/Ge, of polyacrylamide (PAAM) gels was studied. This ratio is directly related to a scaling exponent, δ, which is related to the concentration dependence of both bulk modulus and shear modulus. It was found that δ depends on the details of chemical ingredients and process.

Polyacrylamide
Polyacrylamide can be supplied in a powder or liquid form, with the liquid form being subcategorized as solution and emulsion polymer. Even though these products are often called 'polyacrylamide', many are actually copolymers of acrylamide and one or more other chemical species, such as an acrylic acid or a salt thereof.
Characteristic resonances arising from the acrylamide oligomers are observed between 1.5–2.5 and 6.5–8.0 ppm, respectively (Fig. 4A ). The new purification protocol yields highly pure RNA without any acrylamide contamination, as seen in Figure 4B . Resonances in the imino “fingerprint” region (10–14 ppm) display the same pattern, indicating that both RNAs are folded in the same conformation, which was also confirmed by collection of 2D NOESY spectra (data not shown).

Sodium polyacrylate (also called acrylic sodium salt polymer) is a superabsorbent polymer that is used extensively in commercial applications as a water absorbent. It is a white, granular, odorless solid that is not considered hazardous. Sodium polyacrylate is made when a mixture of acrylic acid and sodium acrylate is

- Can cationic polyacrylamide be used in oilfield wastewater treatment?
- Author to whom correspondence should be addressed. Cationic polyacrylamide (CPAM) solid particle is one of the most commonly used organic polymer flocculants in oilfield wastewater treatment, but it poses some problems, such as a slow dissolution rate and an easy formation into a “fish-eye” in the process of diluting into aqueous solution.
- What is polyacrylamide (PAM)?
- Polyacrylamide (PAM) possesses unique characteristics, including high water solubility, elevated viscosity and effective flocculation capabilities. These properties make it valuable in various sectors like agriculture, wastewater treatment, enhanced oil recovery, and mineral processing industries, contributing to a continually expanding market.
