Anionic and cationic polyacrylamide are two types of polyacrylamide polymers with different charge properties. Here are the main differences between them: 1. Charge properties: The key distinction lies in their charge characteristics. Anionic polyacrylamide has a negative charge due to the presence of anionic groups (such as carboxylate or sulfate groups), while cationic polyacrylamide has a ...

Can polyacrylamide aqueous dispersion be soluble after polymerization?

However, after polymerization, the resulting copolymer should not be soluble in the dispersion medium. The first non-ionic monomer used in aqueous media was acrylamide, which can be copolymerized with anionic and cationic monomers to produce an ionic polyacrylamide aqueous dispersion system .

Can anionic polyacrylamide be used in water treatment?

What's more, the authors discussed the application status of anionic polyacrylamide in water treatment. Based on these reviews, future research perspectives relating to its synthesis and application were proposed. This review summarizes the synthesis methods for anionic polyacrylamide.

Can hydrophobic associative polyacrylamide be polymerized by aqueous dispersion polymerization?

Hydrophobic associative polyacrylamide synthesized by aqueous dispersion polymerization can be polymerized using cationic monomers in combination with acrylamide and hydrophobic monomers, as well as copolymerized with anionic monomers alongside acrylamide and hydrophobic monomers.

What is water soluble polymer dispersion?

posited in the reaction system by salting-out effect to form dispersion which can be dissolved rapidly in water. The resulting system was usually called “water-soluble polymer dispersion” or “hydrophilic polymer dispersion” , and
