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.

What is a polyacrylamide (PAM)?

1. Introduction Polyacrylamides (PAM) are high molecular weight polymers deriving from the polymerization of acrylamide monomers. Their chemical composition and ionic character depend on the functional groups added to the acrylamide chemical moiety (Abidin et al., 2012; Acharya et al., 2010).

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.

Does microblock structure enhance reactivity and copolymerization of Apam-T?

Anionic polyacrylamide with regular microblock structure was synthesized. The reactivity and copolymerization degree were enhanced by microblock structure. The turbidity removal of APAM-T for hematite wastewater could reach 98.22 %. The charge neutralization and bridging adsorption capacity of APAM-T were enhanced.
