N-Vinylpyrrolidone is a colorless to yellowish liquid, with a characteristic odor. It is miscible in water and organic solvents. It is the precursor to polyvinylpyrrolidone (PVP), an important synthetic material. The NVP monomer is commonly used as a reactive diluent in ultraviolet and electron-beam curable polymers applied as inks, coatings or adhesives.
