controlled polymerization of acrylamide via one-pot and one-step

Controlled Polymerization of Acrylamide via One-Pot and One-Step

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. To overcome the above challenges, herein, we report the successful synthesis of well

Optimizing the Conditions of Cationic Polyacrylamide Inverse Emulsion

The polymerization was slowed down, leading to excess monomer, and the molecular weight was reduced. Based on the response surface methodology in Figure 10 a,b,e,f, when the reaction temperature increased from 55 ¡ãC to 60 ¡ãC, the molecular weight of polyacrylamide cations increased rapidly, and reached its maximum at 60¨C62 ¡ãC.

Thus, to achieve a desired average molecular weight, the manufacturer has to work at proper monomer concentration and adapt the process (temperature, initiator, etc.). For low to medium molecular weight polymers (10 3 ¨C10 6 g¡¤mol ?1), the process uses water as a solvent.

The Initial temperature was 7 ¡ãC, and the maximum heating rate was 4.5 ¡ãC/min. The standard deviation of agitation speed was ¡À10 r/min. The standard deviation of molecular weight was ¡À0.3 million. Figure 6 shows that the molecular weight of the polymer was increased gradually by increasing the stirring speed from 250 r/min to 400 r/min.

Figure 8 showed that the molecular weight increased slowly at the urea concentration ranging from 0.05% to 0.4% and then decreased sharply at the urea concentration above 0.4%. The highest molecular weight of 800 ¡Á 10 4 was obtained when the concentration of urea was equivalent to 0.4%. The changes of molecular weight can be interpreted as

The polyacrylamide resin can also be autoclaved at pH 5.5-6.5 for 30 minutes at 120¡ãC. These columns use a resin whose beads have a wet diameter of 45 to 90 ¦ÌM, and are ideal for separating peptides and small macromolecules (greater than 1.8 kDa) from buffer salts and other compounds (less than 500 MW).
