Description and Uses

Norbornene is used as a monomer and as an intermediate in organic synthesis. It is also used to prepare pharmaceutical intermediates and specialty fragrances. It reacts with ethylene to get cyclic olefin copolymer. Further, it is used in transition metal catalysis to affect migration of electrophilic transition metals. It acts as a monomer in ring-opening metathesis polymerizations with the Grubbs' catalyst. Its polymer, polynorbornene is used in the rubber industry for anti-vibration, anti-impact in personal protective equipment and grip improvement in toy tires, racing tires and transmission system.
