Polyacylamides are high molecular weight water soluble or swellable polymers formed from acrylamide or its derivatives. Their glass transition temperature is well above room temperature (> 400 K). The only commercially important polyacrylamide is poly(2-propenamide) which is simply called polyacrylamide or PAM [-CH 2 CH(CONH 2)-]. It is a non-ionic, watersoluble, and biocompatible polymer that can be tailored to meet a broad range of applications.

Polyacrylamide industrial use: polyacrylamide (PAM) with high molecular weight,good water solubility, molecular weight and can be adjusted, the introduction of various ionic groups in order to obtain a specific performance. Low molecular weight is dispersed material effective thickener or stabilizer, high molecular weight flocculant is important, it can produce hydrophilic and water insoluble gel,which for many groups of surface dissolved material has good adhesion.
The effect of polyacrylamide charge density and molecular
In the case of high molecular weight anionic polymers, the settling rate observed was faster than with the cationic polymers. Because the kaolinite has a negative zeta potential this prevents the strong adsorption of anionic polymers, leaving long polymer chains to form bridges with other particles and resulting in large flocs (see Section 4.4). On the other hand, increasing the anionic charge density up 35% in the case of A130 and A130LMW flocculants will reduce the settling rate.
