Norbornene or norbornylene or norcamphene is a bridged cyclic hydrocarbon. It is a white solid with a pungent sour odor. The molecule consists of a cyclohexene ring bridged with a methylene group in the para position. The molecule carries a double bond which induces significant strained and significant reactivity.

Norbornene is made by a Diels-Alder reaction of cyclopentadiene and ethylene. Many norbornene derivatives can be synthesized from Diels-Alder reactions. Related bicyclics are norbornadiene which has the same carbon skeleton but with two double bonds and norbornane which is completely saturated without double bonds. The Diels-Alder reaction is an organic chemical reaction (specifically, a cycloaddition) between a conjugated diene and a substituted alkene, commonly termed the dienophile to form a substituted cyclohexene system. ...

INEOS Oxide - Products - Ethylidene Norbornene (325 words)
The use of ENB is derived from the norbornene double bond which copolymerises with ethylene and propylene to produce an ethylene-propylene-terpolymer that contains the ethylidene double bond as residual unsaturation.
Novel norbornenes, pioneered by INEOS Oxide, are also being used in a host of emerging technologies including high performance cyclic olefin copolymers for electronic and optical applications, in new types of EPDM rubbers, in agrochemicals and in pharmaceuticals.
Laboratory and small pilot plant reaction/distillation facilities are available for the manufacture of novel bespoke norbornenes, based on the reaction of dicyclopentadiene with a host of unsaturated compounds.
