Description

Description générale

4-Vinylpyridine is a highly reactive alkene monomer due to the presence of a vinyl group and a heteroaromatic ring. It is widely used as a monomer to produce a variety of polymers and copolymers, which are used in various applications including, contact lenses, nanoelectronics, sensors, optoelectronic devices, smart coatings, drug delivery systems, sensors, gas separation, air filtration, and purification processes.

Application

4-Vinylpyridine can be used as a monomer:

• In the synthesis or modification of polymers for drug-releasing contact lenses.
• In the preparation of the zwitterionic polymer, namely poly(4-vinylpyridine propylsulfobetaine). The zwitterionic polymer is utilized for its superior bioinert capability in withstanding clinical sterilization processes, making it suitable for extended medical applications which include the development of biocompatible implants and as a coating material for medical devices.
• To synthesize the temperature and pH-sensitive copolymer, specifically (N-vinylcaprolactam-co-4-vinylpyridine), which is used in drug delivery systems under certain environmental conditions.
• The highly charged p(4-vinylpyridine-co-vinylimidazole) particles, which find applications in various fields such as biomedical, catalysis, and environmental applications.

4-Vinylpyridine also plays a role as a functional monomer in the molecular imprinting of the soft contact lens material. Its inclusion, along with other monomers, enhances the affinity of the hydrogel towards brimonidine, resulting in improved binding properties, loading capacity, and controlled release characteristics.
