Polymerization of acrylamide with formation of imide bridges between the macromolecules.

The polymerization of acrylamide (AA) is significantly affects the pH of the reaction medium. At low pH and high temperatures, formation of water-insoluble cross-linked polymers is possible due to the creation of imide bridges between the macromolecules (-CO-NH-CO-). Polyacrylamide-PAA crosslinking reactions (formation of three-dimensional structures) are used to obtain water-absorbing products, films, protective coatings and capsules for drugs, seeds, fertilizers. Increased interest in acrylamide and its practical significance are also associated with some of its complexing properties.
