Is Apam-t a novel anionic polyacrylamide?

Conclusion APAM-T is a novel anionic polyacrylamide which has been successfully synthesized by ultrasonic initiated template copolymerization. Characterization results showed the evidence of the microblock structure’s existence and the enhancement of copolymerization degree by adding the template.

Can UV-initiated template polymerization prepare a novel anionic polyacrylamide with a microblock structure?

E-mail: [email protected]; Fax: +86 23 65120827; Tel: +86 23 65120827 Ultraviolet (UV)-initiated template polymerization (UTP) was used as a feasible strategy to prepare a novel anionic polyacrylamide (APAM) with a microblock structure.

What is anionic polyacrylamide (Apam) powder used for?

Application: Anionic polyacrylamide (APAM) powder is versatile and widely used in sludge dewatering, wastewater treatment, papermaking, water clarification, oilfield applications, textile sizing, and as a versatile polymer for thickening, flocculation, stabilization, adhesion, and biomedical materials.

How is anionic polyacrylamide synthesized?

Synthesis mechanism The anionic polyacrylamide was synthesized by copolymerizing AM and SAS monomers. The essence of copolymerization is the free radical reaction. Thus, this chain reaction can be divided into three distinct processes: initiation, propagation, and termination.

What is anionic polyacrylamide used for?

Polyacrylamide finds applications in pulp and paper production, agriculture, food processing, mining, and as a flocculant in wastewater treatment. Anionic polyacrylamide is suitable for high concentrations of positively charged inorganic suspensions, as well as coarse suspended particles (0.01-1mm), with a Ph value of neutral or alkaline solution.

Is Apam a uniform polymer?

The polyacrylamide is a uniform and unitary polymer. PAM has a neat smooth surface as its SEM images unfold at 2500x and 4000x. However, the surface of APAM was much rougher. Hills and valleys could be observed in its SEM images due to the interaction of chemical groups between AM and SAS.
