Poly(N-vinylacetamide) (PNVA) is a polymer having affinity for both water and alcohol made primarily from N-vinylacetamide (NVA) monomer. The homopolymer of NVA is called GE191 grade. Copolymer of NVA and sodium acrylate called GE167 grade.

History

Showa Denko succeeded in industrialization for the first time in the world. [1]
