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
recent achievements in polymer bio-based flocculants for low cost,this dose was much lower than needed when using polyacrylamide flocculant for the same solution. in other work , it was established that pectin is very effective in kaolin flocculation in the addition of small amount of al(iii) and fe(iii) ions (0.1–0.2 mm). however, in this casem the pectin dose was higher (30 mg/l).
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.
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
as a c3 building block, 3-hydroxypropionic acid offers potential in a variety of chemical conversions such as acrylamide or acrylic acid. acrylamide is obtained by amidation of 3-hydroxypropionic acid with ammonia (gas or aqueous solution), and the 3-hydroxypropioamide thus obtained is dehydrated under high temperature to produce acrylamide .

smaller proteins move at the front or form diffuse, fast-moving bands, whereas larger proteins hardly enter the gel, if at all. electrophoresis of larger proteins requires gels of larger pore size, which are made by dilution of the stock acrylamide solution (reduction of %t) or by adjustment of %c (the smallest pore size is at 5%c, whatever the
