N-Vinylformamide is primarily used as a reactive monomer in polymer synthesis. It serves as a key intermediate for producing water-soluble polymers and copolymers with tailored properties. Due to its ability to undergo free radical polymerization, it is commonly employed in the manufacture of specialty polymers used in coatings, adhesives, and textile treatments. It is also utilized in the preparation of cationic polymers for use in water treatment and enhanced oil recovery. Its functional group allows for further chemical modifications, making it valuable in creating responsive or stimuli-sensitive materials for industrial and biomedical applications.
