This is introduced using acrylamide or methacrylamide monomers. Once this was the most commonly encountered method of building a cross-linkable polymer system. However, with the advent of a wider range of commercially available functional monomers the use of acrylamide and methacrylamide is now not so prevalent in polymers for surface coating application.

Acrylamide is now regarded as an extremely toxic and hazardous material. This fact has contributed to declining usage. Unlike most acrylic monomers it is a solid at room temperature. Care must be exercised when using and handling acrylamide to avoid contact with, and the generation of, acrylamide dust.
