Polyacrylamide | 9003-05-8 - ChemicalBook
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.

Get PriceWhat is polyacrylamide (PAM)?
Polyacrylamide (PAM) possesses unique characteristics, including high water solubility, elevated viscosity and effective flocculation capabilities. These properties make it valuable in various sectors like agriculture, wastewater treatment, enhanced oil recovery, and mineral processing industries, contributing to a continually expanding market.
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 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.
What is a polyacrylamide & oligomer?
Polyacrylamide (PAM) & oligomers PAM is a water-soluble, odorless, white synthetic linear polymer with the repeating formula (-CH 2 CHCONH 2 -), and its monomer used is AM. Its molecular weight (MW) of PAM ranges from 10 5 to >10 7 Da, with a length of up to six million monomer units.
How dangerous is polyacrylamide (PAM)?
4.1.1. Polyacrylamide (PAM) As PAM is extensively used in our daily lives, it is essential to be aware of its potential hazards. Studies have indicated that PAM exhibits low or non-toxicity to humans, primarily due to the large sizes of polymers, which restrict their ability to penetrate the skin.
Is polyacrylamide water soluble?
Polyacrylamides are high molecular weight water soluble or swellable polymers formed from acrylamide or its derivatives. Their glass transition temperature is well above room temperature (> 400 K). Polyacrylamide PAM is currently the most widely used synthetic organic polymer flocculant, and sometimes it is also used as a coagulant aid.
