Used primarily as a monomer in the synthesis of specialty polymers and copolymers, particularly in ring-opening metathesis polymerization (ROMP) processes. Its unique bridged bicyclic structure with a reactive vinyl group enables the production of polymers with high thermal stability and tailored mechanical properties. Commonly employed in advanced materials for microelectronics, such as low-dielectric-constant insulators, and in the development of functional coatings and photoresists. Also finds use in crosslinking agents for resins and in the preparation of norbornene-based copolymers for optical and semiconductor applications.
