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] Polyacrylamide is a polyolefin.

Potassium Polyacrylate and Sodium Polyacrylate are both superabsorbent polymers commonly used in various applications. However, they differ in terms of their ionic properties. Potassium Polyacrylate contains potassium ions, while Sodium Polyacrylate contains sodium ions.
What is the density of poly(acrylamide-co-acrylic acid) potassium salt and sodium polyacrylate?
Poly (acrylamide-co-acrylic acid) potassium salt and sodium polyacrylate are both superabsorbent crosslinked polymers having a density of 0.54 g/mL at 25 °C [25, 26]. Figure 3 shows the repeating terms of the chemical structures of both poly (acrylamide-co-acrylic acid) potassium salt and sodium polyacrylate used in this study.
Is potassium polyacrylate a polymer?
Potassium polyacrylate is a polymer composed of repeating units of acrylic acid and potassium ions. The potassium ions are responsible for providing the polymer with its unique properties. On the other hand, sodium polyacrylate is composed of acrylic acid units and sodium ions.
Do sodium polyacrylate and potassium salt swell?
This study experimentally evaluated the swelling performance of two SPHs, poly (acrylamide-co-acrylic acid) potassium salt and sodium polyacrylate, based on their stimuli response to pH, salinity concentration, temperature and reaction time periods. Several important conclusions have emerged:
Does potassium polyacrylate have a higher absorption capacity?
However, potassium polyacrylate has been found to have a higher absorption capacity compared to sodium polyacrylate. This is due to the larger size of potassium ions, which allows for more efficient water retention within the polymer structure.
