synthesis and characterization of acrylamide‐based anionic
acrylamide is a hydrophilic and nonionic monomer and has high rate constant for polymerization in water. 2-acrylamido-2-methyl-1-propane sulfonic acid (amps) as the anionic monomer has high reactivity and good hydrolytic stability due to the geminal dimethyl groups and ionization even at low ph values.

spotlight on the life cycle of acrylamide-based polymers
as a c3 building block, 3-hydroxypropionic acid offers potential in a variety of chemical conversions such as acrylamide or acrylic acid. acrylamide is obtained by amidation of 3-hydroxypropionic acid with ammonia (gas or aqueous solution), and the 3-hydroxypropioamide thus obtained is dehydrated under high temperature to produce acrylamide .
