Used primarily as a monomer in the synthesis of specialty polymers and copolymers, 2-vinylnaphthalene contributes to materials with enhanced thermal stability and rigidity due to the bulky naphthalene ring. It is employed in the production of high-performance resins, particularly for applications requiring resistance to heat and oxidation. Its aromatic structure also makes it useful in the development of functional polymers for optical and electronic materials, including certain types of fluorescent sensors and organic semiconductors. Additionally, it serves as a chemical intermediate in organic synthesis, where its reactive vinyl group allows for further functionalization in the construction of complex molecules.
