synthesis and characterization of acrylamide‐based anionic

acrylamide is a hydrophilic and nonionic monomer and has high rate constant for polymerization in water. 2-acrylamido-2-methyl-1-propane sulfonic acid (amps) as the anionic monomer has high reactivity and good hydrolytic stability due to the geminal dimethyl groups and ionization even at low ph values.

dispersion polymerization of anionic polyacrylamide in an,anionic polyacrylamide dispersions were prepared by dispersion polymerization in an aqueous salt medium, using acrylamide(am) and acrylic acid(aa) as monomers and anionic polyelectrolytes as stabilizer. effects of salt concentration, and molecular weight and concentration of stabilizers on the stability of the dispersions were investigated using a haake rheometer and optical microscopy. the

solvent-free anionic polymerization of acrylamide

mechanistic insights into bulk hydrogen-transfer polymerization of acrylamide initiated by t-buona are proposed in this study where attention is particularly given to the initiation and propagation steps. this anionic polymerization methodology led to the synthesis of polyamide-3 with controlled molar masses. nmr, sec, and maldi-tof characterizations are supporting the chemical structures and

controlled polymerization of acrylamide via one-pot and one,copper-catalyzed controlled polymerization of acrylamide 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. to overcome the above challenges, herein, we report the successful synthesis of well

spotlight on the life cycle of acrylamide-based polymers

the inverse emulsion (co)polymerization based on acrylamide consists of the dispersion of water droplets containing the monomers into an oil phase with the help of surfactants. the monomer concentration can be increased up to 40% due to a redox initiation at room temperature, permitted by the presence of a water thermal sink allowing heat

using polyelectrolyte polymers in water treatment,however, good secondary dilution must absolutely be undertaken at the feeding pump delivery point (100 to 200 times dilution in-line) using low salinity clean water (if possible, salinity below 200 mg · l –1).

acrylamide‐based anionic polyelectrolytes and their

water-soluble polymers are found in a very broad range of industrial applications. an important class of these is acrylamide-based polymers which bear negative charges along the polymer chain and are called anionic polyelectrolytes. these negatively charged polymers are widely used as flocculants, rheology control agents, and adhesives.
