Polyacrylamide

Polyacrylamide (IUPAC poly(2-propenamide) or poly(1-carbamoylethylene) abbreviated as PAM) is a polymer (-CH 2 CHCONH 2-) formed from acrylamide subunits It can be synthesized as a simple linear-chain structure or cross-linked typically using N N '-methylenebisacrylamide In the cross-linked form the possibility of the monomer being present is reduced even further
