Is polyacrylamide a water soluble polymer?

Polyacrylamide (PA), a water-soluble linear polymer, is composed of acrylamide monomers or a combination of acrylamide and acrylic acid monomers.

What is polyacrylamide used for?

Polyacrylamide has effects of flocculation, thickening, drag reduction, adhesive, colloidal stabilizing, filming and preventing scale. It is widely used in papermaking, mining, coal washing, metallurgy, oil exploitation and other industrial sectors and is also a important chemical for water treatment. Figure 1 The synthetic route of polyacrylamide.

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 are the effects of polyacrylamide & amide group?

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

What is a polyacrylamide (PAM)?

Polyacrylamides (PAMs) are relatively inexpensive polymers that are easily formulated to high molecular weights on the order of several million g/mol. PAM was first used in the paper industry in the mid-1950s.

Does polyacrylamide undergo photodegradation?

Polyacrylamide undergoes thermal degradation at 175 to 300°C (Smith et al., 1996) and can also undergo photodegradation. Acrylamide is readily biodegraded under aerobic conditions by microorganisms in soil and water by deamination to acrylic acid and ammonia, which are utilized as carbon and nitrogen sources.
