what are the physical properties of anionic polyacrylamide

For industrial use flocculant is concerned, it must have a unique physical properties and chemical properties, in order to achieve the effect of high-flocculation treatment of sewage. Three is called anionic polyacrylamide flocculant, which is formed by the polymerization of acrylamide monomer, is a water-soluble linear polymers as a white powder, odorless, soluble in water, almost insoluble in benzene, ether, esters, acetone and other organic solvents, aqueous almost nearly transparent viscous liquid, non-corrosive, non-toxic, solid polyacrylamide strong hygroscopicity, which increases with the degree of ion-enhanced, in addition , PAM good thermal stability, the average molecular weight of from thousands to tens of millions or more hook-shaped elements along with certain functional groups, the majority of the water can be ionized, the polymer electrolyte are heated to 100 ° C was stable at 150 degree than is easy to produce nitrogen imidization occurs in intermolecular interaction but do not dissolve in water, which exhibit non-Newtonian flow properties under stress.
