Acrylamide will polymerize with itself and copolymerize with many other vinyl monomers. The resulting polymers may then be modified through reaction of the amide group.
Alkaline hydrolysis of acrylamide polymers introduces carboxylate ions thereby forming polyelectrolytes. On the other hand, acid treatment produces imidized products whose water solubility decreases with increasing imidization.
Decreased water solubility also results from reaction of acrylamide polymers with
formaldehyde followed by curing. The actual solubility depends upon the degree of methylolation.
Acrylamide polymers will react with chlorine to give products having increased hardness, higher softening points, and reduced flammability.
These modifications suggest many new applications for polymers containing acrylamide—polymers that can play an important role in your new product plans. Further details are presented in "Chemistry of Acrylamide." Write for your copy.
