Is acrylamide a soluble polymer?

Poly (acrylamide) is a water-soluble polymer made up of acrylamide subunits. Polyacrylamides have been reported to be protein resistant and biocompatible. Polyacrylamides have been used as carriers for delivery of drugs and bioactive compounds, or to as tissue engineering materials.

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.

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 the difference between polyacrylamide and other flocculants?
