High-purity vinyl monomer for advanced polymer synthesis and functional material applications
2-Vinylpyridine (C₇H₇N) is a high-purity vinyl monomer (97%) widely used in polymer synthesis for producing homopolymers and copolymers with tailored chemical and physical properties. This water-soluble pyridine derivative features a vinyl group directly attached to a pyridine ring, enabling anionic, radical, and coordination polymerizations. It is stabilized with 0.1% p-tert-butylcatechol to prevent premature polymerization during storage.
2-Vinylpyridine-based polymers exhibit pH-responsive behavior, ion-binding capability, strong adhesion to various substrates, and tunable surface functionality, making them suitable for membranes, coatings, sensors, energy storage devices, and drug delivery systems.
