What is polyacrylamide (PAM)?

Explore the versatile world of Polyacrylamide (PAM), its synthesis, properties, uses across various industries, and safety concerns. Polyacrylamide, often abbreviated as PAM, is a synthetic high molecular weight polymer with a significant role in several industries. It is composed of acrylamide monomers, hence its name.

What is polyacrylamide polymer?

It is composed of acrylamide monomers, hence its name. The characteristics of PAM vary greatly depending on the level of polymerisation, making it an extremely versatile compound. Polyacrylamide is a linear polymer chain with recurring acrylamide subunits.

What is glyoxalated polyacrylamide (G-Pam)?

Summary: Glyoxalated polyacrylamides (G- PAM) provide an alternative chemistry to other papermaking resins additives for wet and dry strength. This new generation of G-PAM provides a better compromise between wet end chemistry performance and paper dry strength targets along with logistical benefits of shipping concentration and shelf life.

What is the standard state of polyacrylamide?

Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ?) Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated.

What is hydrolyzed polyacrylamide (HPAM)?

Hydrolyzed polyacrylamide (HPAM), a derivative resulting from the hydrolysis of PAM, demonstrates significant thickening capabilities in freshwater and at relatively lower temperatures (<75 °C) due to strong intra- and inter-chain electrostatic repulsion of carboxylate groups 14.

Can polyacrylamide contribute to residual polymer formation?

Common methods for treating PAM are membrane filtration 25, thermal distillation 24, oxidation treatment 26, and biological treatments 27. However, addressing the challenge posed by PAM remains a pressing issue within the industry. Fig. 1: Polyacrylamide and its fragments may contribute to residual polymer formation.
