Flocculants - an overview
The vast majority of commercial flocculants are based on copolymers of acrylic acid and polyacrylamide (also referred to as hydrolyzed polyacrylamide): As a result of hydrolysis even ‘non-ionic’ polyacrylamides contain some anionic groups.

Hydrolyzed polyacrylamide grafted carboxymethylstarch (Hyd
A high performance polymeric flocculant has been developed by partial alkaline hydrolysis of polyacrylamide grafted carboxymethylstarch (CMS-g-PAM). The optimized grade was determined through its higher intrinsic viscosity in solution. Various grades of this hydrolyzed graft copolymer were prepared by varying the reaction parameters.

The Flocculation between Partial Hydrolyzed Polyacrylamide
These particles formed flocs with hydrolyzed polyacrylamide through electrostatic attraction. The structure of these flocs evolved from a bulk state to insulated microspheres at a critical salt concentration, which increased with increasingly cationic degree of particles, corresponding to the change of Zeta potential.

The difference of anionic, cationic and Non-ionic polyacrylamide
Polyacrylamide is not the only acrylamide unit, the acrylamide unit is mostly called polyacrylamide. Thus, polyacrylamide may contain structural units that can be ionized or hydrolyzed in water to carry charges. As a result, there are cationic, anionic, non-ionic, amphoteric ion type of various polyacrylamide anionic polyacrylamide。(
