N-Vinylacetamide (NVA) is a non-ionic monomer. Copolymers made of NVA and other monomers can exhibit practical characteristics in addition to those common with the existing hydrophilic polymers.
History[edit]
NVA is an amphipathic monomer. It was introduced and compounded in the U.S. in 1967. Today, it is recognized as a monomer that does polymerize; however, Showa Denko K.K. succeeded in its industrialization in 1997.[1]
Properties[edit]
NVA is soluble in water, various organic solvents and liquid vinyl monomers. It is polymerizable by various radical polymerization processes, depending on the objective. Since NVA itself is a solvent, it can act as a dissolution agent for poorly soluble substances.
