trends in polyacrylamide utilization and treatment for low cost

cationic polyacrylamide (cpam), copolymerized from acrylamide and substituted acrylate or acrylamide segments, offers an alternative to phpa and exhibits high stability under high tds conditions.

polyelectrolyte gels: fundamentals, fabrication for free sample,as an anionic drug (such as zol) encounters negative charges on the outer shell of a pec with a mixing ratio of q 1.1 (anionic system), this leads to electrostatic repulsion.

controlled polymerization of acrylamide via one-pot and one

to achieve successful cu-catalyzed polymerization of a particular monomer targeting controlled mw s and mwds, appropriate selection of the reaction parameters (e.g., initiator, ligand, solvent, and the amount of deactivator etc.) is crucial.

research on a new cationic polyacrylamide (cpam) with high purity,in this paper, the template copolymer of acryloxy trimethylammonium chloride (dac) and acrylamide was successfully synthesized by microwave-template copolymerization (mv-tp) using sodium polyacrylate (napaa) as template.

spotlight on the life cycle of acrylamide-based polymers

polyacrylamide copolymers, either anionic or cationic, are potentially quickly converted to corresponding polyacrylate salts by deamination or hydrolysis. therefore, biodegradation of related polyacrylic acid (or related salts) provides insights in polyacrylamide biodegradation and their fate.
