Polyelectrolyte polymers—Types, forms, and function
A more practical approach involving copper-based catalysts was developed and used through the early 1980s and 1990s [12], [13], [14]. Since that time, the use of enzymes (known as nitrile hydratase) has more or less supplanted the earlier methods of acrylamide manufacture yielding a bioderived acrylamide (often called Bio-AMD) [15].
