The copolymer of acrylamide (AM) and 2-acrylamido-2-methyl-1-propane sulfonic acid (AMPS) was synthesized through radical solution polymerization by potassium persulfate as initiator. By changing the AMPS feed ratio from 10 to 70%, and keeping other reaction conditions constant, diferent copolymers were synthesized.

Intrinsic and apparent viscosity of samples were measured in aqueous sodium chloride solution under standard conditions. The anionic degree of copolymers was determined by back titration method and by 13 C-NMR spectroscopy. Molecular weight of copolymers was determined by the Mark-Houwink relationship.

Get PriceWhat are the different types of anionic polyacrylamide synthesis technologies?
The paper lists six different kinds of anionic polyacrylamide synthesis technologies, including homopolymerization posthydrolysis process, homopolymerization cohydrolysis process, copolymerization approach, inverse emulsion polymerization, precipitation polymerization and radiation polymerization.
Can anionic polyacrylamide be used in water treatment?
What's more, the authors discussed the application status of anionic polyacrylamide in water treatment. Based on these reviews, future research perspectives relating to its synthesis and application were proposed. This review summarizes the synthesis methods for anionic polyacrylamide.
Can polyaluminium chloride and anionic polyacrylamide remove CD 2+ and Zn 2+?
Water treatment residuals produced after addition of polyaluminium chloride and anionic polyacrylamide (PAC-APAM WTRs) were evaluated for the potential to remove Cd 2+ and Zn 2+ from aqueous solutions by batch adsorption studies.
What is anionic polyacrylamide (PAM)?
Anionic polyacrylamide (PAM) possesses interconnected and active groups that establish robust bonds with the surface of suspended colloids, promoting the formation of coarse particles among the suspended solids and a mixture of insoluble particles in water (Irfan et al. 2017).
Can anionic polyacrylamide be used as a coagulant in water treatment sludge?
Also, using anionic polyacrylamide (APAM) as a coagulant in the dewatering process of water treatment sludge has been a regular practice to accelerate the dewatering process and decrease the size of dewatering tanks or ponds in large-scale drinking water treatment plants.
How are water soluble acrylmide-based anionic copolymers prepared?
4. Conclusions Water soluble acrylmide-based anionic copolymers were prepared by free radical solution polymerization. By changing the AMPS monomer feed ratio from 10 to 70 weight percent, while keeping other reaction conditions constant, different anionic copolymers were synthesized.
