Poly vinyl amide.

Poly n vinylacetamide pnva is a polymer having affinity for both water and alcohol made primarily from n vinylacetamide nva monomer. It can be synthesized as a simple linear chain structure or cross linked typically using n n methylenebisacrylamide. Copolymer of nva and sodium acrylate called ge167 grade. In the cross linked form the possibility of the monomer being present is.
