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 .

What are the different types of anionic polyacrylamide synthesis technologies?

The paper lists six different kinds of anionic polyacrylamide synthesis technologies, including homopolymerization posthydrolysis process, homopolymerization cohydrolysis process, copolymerization approach, inverse emulsion polymerization, precipitation polymerization and radiation polymerization.

What is aqueous dispersion polymerization (ADP)?

Aqueous dispersion polymerization (ADP) is a method of polymerization based on the mechanism of free radical polymerization. It involves dissolving monomers, initiators and dispersing agents in a dispersion medium to form a clear and transparent homogeneous solution.

How does polymeric aluminum chloride achieve destabilization?

Polymeric aluminum chloride (PAC) achieves the destabilization process by adsorbing onto the surface of colloidal particles and facilitating bridging. Consequently, when PAC executes both destabilization mechanisms concurrently, the process becomes more rapid and results in superior separation.

What is dispersion polymerization?

Dong et al . were the first to use dispersion polymerization technology to prepare a hydrophobic association polyacrylamide derivative with good water solubility and a relative molecular mass reaching over a million using monomers such as acrylamide.

Does aqueous dispersion polymerization use organic solvents?

Aqueous dispersion polymerization does not use organic solvents in the preparation process of HAPAM, which is beneficial for environmental protection. Likewise, the synthesized products possess good fluidity, stability, high solid content and high molecular weight, among other advantages.
