What is anionic polyacrylamide (Apam) synthesis technology?

Anionic polyacrylamide (APAM) was first developed in the world through an alkali hydrolysis process. So far, APAM synthesis technology has undergone a lot of development. In this study, synthesis poly (sodium acrylate-co-acrylamide) was performed as flocculant which will be used in the sugar refining process.

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: zhl6512@126.com; 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.

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.

Why is anionic polyacrylamide flocculant a problem?

One of the problems that occur is due to the large number of imported raw materials including flocculants, which in this case is anionic polyacrylamide flocculants. Anionic polyacrylamide (APAM) was first developed in the world through an alkali hydrolysis process. So far, APAM synthesis technology has undergone a lot of development.

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.
