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.
As an example, the alternating copolymerization of 2-phenyl-1,3,2-dioxaphospholane (81a) can be used. Thus, the copolymerization of structure 81a with acrylic acid (87) and with β-propiolactone (88) gives the same alternating copolymer (90). 153 The M-A reaction is responsible for the appearance of the tetracoordinated phosphorus.

Acrylamide is a common monomer for various copolymers as well as in regular polyacrylamide gels. For example, copolymers of acrylamide and allyl gluconic lactobionic acid can be used to self-coat the capillary wall, allowing DNA fragments to be efficiently separated in an uncoated capillary [54] .

Polyacrylamide is also used in water, sewage and waste treatment, oil recovery, ore processing paper making, and to make permanent-press fabrics, to synthesize dyes, contact lenses, and in the construction of dams, tunnels and sewers (Habermann 2002). [7] Polyacrylamide is also present in cigarette smoke.
Zwitterionic Polyacrylamide [Features] Zwitterionic polyacrylamide is copolymerized by the copolymerization of cationic monomer, acrylamide monomer and hydrolytic agent. This product is a kind of atactic polymer with molecular chain of both positive and negative charged zwitterions.

The United States is taking various new polymer materials as the research object. Russia is mainly based on the principle that “the raw materials are cheap and easy to obtain”, and various industrial wastes. Chinese research focuses on the full use of traditional raw materials and the development of new synthetic polymers (including monomers).
Other materials are also used to make a superabsorbent polymer, such as polyacrylamide copolymer, ethylene maleic anhydride copolymer, cross-linked carboxymethylcellulose, polyvinyl alcohol copolymers, cross-linked polyethylene oxide, and starch grafted copolymer of polyacrylonitrile to name a few. The latter is one of the oldest SAP forms created.
