- What is linear anionic polyacrylamide (PAM)?
- Linear anionic polyacrylamide (PAM) has been used in irrigation practices as a flocculating agent to minimize water losses through seepage in earthen canals. The stability of PAM is of concern because of the possibility of acrylamide (AMD) monomer release during Mesenchymal stem cell durotaxis depends on substrate stiffness gradient strength.
- What is anionic polyacrylamide used for?
- Anionic polyacrylamide can be used as a cytoplasm additive in the paper industry with better retention and drainage effect. It has a particularly dispersing effect for long-fiber pulp when its molecular weight is greater than 3.5 million. In addition, it can also be used as a water treatment agent.
- What is polyacrylamide polymer?
- Polyacrylamide, also briefly referred as PAM, is commonly a polymer with acrylamide monomers bonded connected by end to end configuration; it is a hard glassy solid at room temperature. Because of the difference in production methods, the products can be white powder, translucent beads and flaky like.
- Is polyacrylamide soluble in water?
- Polyacrylamide is insoluble in benzene, toluene, xylene, gasoline, kerosene, diesel fuel, but soluble in water. Polyacrylamide can react with alkaline with partial hydrolysis of polyacrylamide. It will have imidization reaction in strongly acidic (pH≤2.5) which will reduce its solubility in water.
