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. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries. [1] Polyacrylamide is a polyolefin.

high molecular weight PAM standard was characterized by AF4-MALS for molecular weight, size and branching. The weight average molecular weight of the polymer was measured as 7.6 MDa with a weight average radius of gyration of 154 nm. The conformation plot suggested high order of branching in the polymer structure.

What is a high molecular weight polyacrylamide (PAM)?

Low molecular weight PAM can be used as a paper strengthening agent. Medium molecular weight polyacrylamide PAM is used as a retention and drainage aid. And high molecular weight polyacrylamide is used as a flocculant in the treatment of papermaking wastewater. At present, anionic PAM is most used in the paper industry.

Which polyacrylamide is used as a pulp dispersant?

Anionic polyacrylamide can be used as a pulp dispersant. Low molecular weight PAM can be used as a paper strengthening agent. Medium molecular weight polyacrylamide PAM is used as a retention and drainage aid. And high molecular weight polyacrylamide is used as a flocculant in the treatment of papermaking wastewater.

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 the molecular weight of Pam?

The molecular weight (MW) of commercial PAM ranges from 10 5 to >10 7 Da. High MW PAM (>10 6 Da) has a wider range of applications due to its high viscosity, drag reduction capabilities, and water retention characteristics. 6, 7, 8 PAM is widely used in environmental systems including: 1. 2. 3.

What is Pam polymer?

PAM is one of the most widely used water-soluble polymer species with a large number of pendant amide groups presenting on its molecular backbone. Amide group has a high chemical activity which can forms a series of derivatives with many kinds of compounds.

What is polyacrylamide polymer?

Polyacrylamide, also briefly referred as PAM, is commonly a polymer with acrylamide monomers bonded connected by end to end configuration; it is a hard glassy solid at room temperature. Because of the difference in production methods, the products can be white powder, translucent beads and flaky like.
