N-Vinyl-2-pyrrolidone丨CAS 88-12-0

N-Vinyl-2-pyrrolidone丨CAS 88-12-0, is a reactive vinyl monomer derived from 2-pyrrolidone. It appears as a clear, colorless to light yellow liquid with a mild odor. The vinyl group makes it suitable for polymerization, while the pyrrolidone ring contributes hydrophilicity, solubility, and biocompatibility. NVP is widely used to manufacture polyvinylpyrrolidone (PVP) and other copolymers in industries ranging from pharmaceuticals to inks and coatings.

1. Production of Polyvinylpyrrolidone (PVP)
● Main Use: NVP is primarily polymerized to form PVP, a water-soluble polymer with applications in pharmaceuticals, cosmetics, adhesives, and food processing.
● Properties of PVP: Biocompatible, non-toxic, adhesive, film-forming, and hygroscopic.
2. Pharmaceuticals and Biomedical Applications
● Drug Formulation: PVP derived from NVP is used as a binder in tablets, a film former in drug coatings, and a carrier for poorly soluble drugs.
● Medical Devices: NVP copolymers are used in hydrogels for contact lenses, wound dressings, and controlled drug release systems due to their non-irritating, non-sensitizing, and moisture-retaining properties.
● Plasma Volume Expanders: PVP solutions have been explored as blood plasma substitutes.
3. Cosmetics and Personal Care Products
● Hair and Skin Products: NVP-based polymers act as film formers, thickeners, and emulsifiers in hair sprays, gels, creams, and lotions.
● Long-lasting Effects: Provides hold and flexibility in hairstyling and enhances moisture retention in skincare products.
4. Adhesives and Sealants
● NVP-derived polymers are used in pressure-sensitive adhesives, medical tapes, and wound care adhesives.
● Offers strong adhesion to skin and surfaces while being non-irritating.
5. Inks, Coatings, and Printing
● UV-Curable Inks and Coatings: N-Vinyl-2-pyrrolidone丨CAS 88-12-0 is used as a reactive diluent and co-monomer in UV-curable formulations for printing, optical discs, and electronic coatings.
● Improves adhesion, gloss, and solvent resistance of printed materials.
6. Textile and Paper Industries
● Finishing Agent: Used to impart antistatic, softening, or binding properties to textiles and paper products.
● Pigment Binders: Enhances print quality and wash resistance in textile printing.
7. Photopolymerization and Electronics
● NVP is a co-monomer in photoresists, 3D printing resins, and photopolymer plates.
● Its hydrophilic and UV-reactive nature makes it ideal in resin formulations for microelectronics, photolithography, and optics.

1. Excellent Polymerization Versatility
● NVP readily undergoes free-radical polymerization and copolymerizes with a wide range of monomers including acrylates, styrene, and methacrylates.
● This makes it a valuable building block for tailoring material properties in polymers.
2. Hydrophilicity and Solubility
● The pyrrolidone ring gives NVP hydrophilic character, making it useful in water-compatible and bio-compatible applications.
● Enhances water retention, swelling, and moisture absorption properties in polymers.
3. Low Toxicity and Biocompatibility
● N-Vinyl-2-pyrrolidone丨CAS 88-12-0 and its polymers are generally non-toxic and well-tolerated in biological systems.
● This makes them suitable for pharmaceutical and medical device applications.
4. Improved Adhesion and Flexibility
● NVP-based polymers exhibit strong adhesion to both hydrophilic and hydrophobic surfaces.
● Offers flexibility, film integrity, and resistance to cracking under stress.
5. Stability and Compatibility
● Chemically stable under a wide range of pH and temperature.
● Compatible with UV-curing, aqueous, and solvent-based systems.

N-Vinyl-2-pyrrolidone丨CAS 88-12-0 is a versatile and valuable monomer with wide-ranging applications across pharmaceuticals, cosmetics, adhesives, inks, and coatings. Its unique combination of polymerization reactivity, hydrophilicity, and biocompatibility allows it to enhance product performance in both technical and consumer-facing industries.
