Cerex

Cerex, also known as 1-vinyl-2-pyrrolidone (NVP), is a vinyl monomer that is a colorless liquid. It is readily soluble in water and many organic solvents. Cerex is primarily used as a monomer in the production of polymers, most notably polyvinylpyrrolidone (PVP).

PVP is a water-soluble polymer with a wide range of applications. It is used in the pharmaceutical industry as a binder in tablets, a disintegrant, and a solubilizer for poorly soluble drugs. In cosmetics and personal care products, PVP acts as a film-former, hair fixative, and emulsifier, found in products like hairspray, gels, and lotions. It also finds use in industrial applications, including adhesives, coatings, and membranes.

The polymerization of cerex to form PVP can be initiated by free radicals. The properties of the resulting PVP, such as molecular weight and viscosity, can be controlled by adjusting the polymerization conditions. Cerex itself is a relatively stable compound under normal storage conditions but can undergo polymerization if exposed to heat, light, or initiators. Due to its reactive nature, proper handling and storage precautions are necessary. Its versatility as a building block for polymers makes it an important industrial chemical.
