- How is polyacrylamide produced?
- Commercially, PAM is produced by hydration of Acrylonitrile (ACN) to produce Acrylamide and then cross-linking polymerization of Acrylamide that produces PAM. During production, Acrylamide is always advised to be handled with care due to its high toxic nature, although after polymerization polyacrylamide become non-toxic.
