Properties of Polyacrylamides

Polyacylamides 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). The only commercially important polyacrylamide is poly(2-propenamide) which is simply called polyacrylamide or PAM [-CH 2 CH(CONH 2)-]. It is a non

Super Water-Absorbing Polymers | Carolina.com

Two common super water-absorbing polymers are sodium polyacrylate and polyacrylamide. Sodium polyacrylate consists of repeating units of the monomer –CH 2 CH(CO 2 Na)–. The sodium ion dissociates in water, leaving 2 charged particles—a free sodium cation and a carboxylate (CO 2 –) ion—attached to the strand.

Stir in a little table salt and the solid becomes liquid again as the polymer chains are broken. At higher ratios of water to powder, 200:1, 300:1 and 400:1, it forms a gel that gets slushier as more water is added. The particles in water gel powder are in the 100-800 micron range, which allows them to very quickly absorb water.
