A linear copolymer of acrylate and acrylamide (nonionic) monomers, also called partially-hydrolyzed polyacrylamide (PHPA).The ratio of acrylic acid to acrylamide groups on the polymer chain can be varied in manufacturing, as can molecular weight. Another variable is the base used to neutralize the acrylic acid groups, usually NaOH or KOH, or sometimes NH 4 OH.

Properties. The hydrated PAM is a soft gel that is used in gel electrophoresis and as a super water-absorbing polymer (SAP's). Even though these polymers are called polyacrylamide, they are often copolymers of acrylamide and one or more other monomers. The most important co-monomer is acrylic acid or sodiumacrylate.
