How is polyacrylamide-CO-sodium acrylate prepared?

Learn more. Polyacrylamide-co-sodium acrylate has been prepared via copolymerization of acrylamide and acrylic acid, or the hydrolysis of a pre-formed nonionic polymer. Both macromolecules had a charge of 24 mol% with a molar mass of 25 million g/mol.

How to control acrylamide polymerization?

To conclude, the controlled polymerizations of acrylamide have been successfully achieved via a one-pot and one-step aqueous Cu (0)-mediated RDRP approach. It has been demonstrated that strong deactivation control is the key for the control in AM RDRPs.

What is copper-catalyzed controlled polymerization of acrylamide?

Copper-catalyzed controlled polymerization of acrylamide (AM) has always been a challenge, which typically exhibits low monomer conversion and broad molecular weight distribution (MWD) or requires complex/multistep reaction procedures, due to the highly active nature of the AM radical and its side reactions.

What are polyacrylamide block copolymers used for?

Polyacrylamide block copolymers has been extensively used in many fields of science and technology due to their water solubility, biocompatibility and…

What is radical copolymerization?

One such useful technique is the radical copolymerization of two types of monomers with similar copolymerization reactivities, which allows the hydrophilicity/hydrophobicity balance in the polymer structure to be easily tuned.

Does synthesis method affect polyacrylamide solution properties and application performance?

The hydrolyzed macromolecules essentially functioned only as a coagulant generating pin flocs. Depending on the application, polymer structure can be tuned by the method of synthesis. To the authors' knowledge, this is the first report comparing the influence of synthesis method on polyacrylamide solution properties and application performance.
