What is Pam polymer?

PAM is one of the most widely used water-soluble polymer species with a large number of pendant amide groups presenting on its molecular backbone. Amide group has a high chemical activity which can forms a series of derivatives with many kinds of compounds.

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 toxic to humans?

Toxicity: Polyacrylamide itself is non-toxic, but if it contains polymerized monomers (a double bond), it would be toxic to humans. For this reason, upon the completion of its preparation, a certain amount of sodium bicarbonate should be added to remove residual monomers. The above information is edited by the chemicalbook of Dai Xiongfeng.

Can polyacrylamide be miscible?

Polyacrylamide can also quickly miscible with non-ionic, cationic and anionic surfactants, though with certain surfactants affecting the viscosity. Viscosity: The viscosity of polyacrylamide solution has a linear correlation with its molecular weight; in addition, the higher the temperature, the lower the viscosity.

What is polyacrylamide used for?

Polyacrylamide has effects of flocculation, thickening, drag reduction, adhesive, colloidal stabilizing, filming and preventing scale. It is widely used in papermaking, mining, coal washing, metallurgy, oil exploitation and other industrial sectors and is also a important chemical for water treatment. Figure 1 The synthetic route of polyacrylamide.

Is polyacrylamide soluble in water?

Figure 1 The synthetic route of polyacrylamide. Polyacrylamide is relatively stable to heat with its solid only being softened at 220~230 °C and its solution subjecting to significant degradation only at above 110 °C. Polyacrylamide is insoluble in benzene, toluene, xylene, gasoline, kerosene, diesel fuel, but soluble in water.
