What is anionic polyacrylamide (Apam)?

Anionic Polyacrylamide (APAM) has a linear-chain structure. Amide group has a high chemical activity which can forms a series of derivatives with many kinds of compounds. Anionic Polyacrylamide (APAM) has effects of flocculation, thickening, drag reduction, adhesive, colloidal stabilizing, filming and preventing scale.

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.

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.

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.

What is the difference between Pam and Apam?

A number of significant differences were found between those three polymers. 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.

What does Apam stand for?

Anionic Polyacrylamide (APAM) (abbreviated as PAM or pAAM) is a polymer with the formula (-CH2CHCONH2-). Anionic Polyacrylamide (APAM) has a linear-chain structure. Amide group has a high chemical activity which can forms a series of derivatives with many kinds of compounds.
