Vinyl norbornene

Vinyl norbornene is an organic compound. It is used to make ethylidene norbornene, an ingredient in some types of rubber.

 Preparation 
Vinyl norbornene can be made from the Diels-Alder reaction of butadiene and cyclopentadiene.

 Uses 
The main use of vinyl norbornene is changing it into its isomer, ethylidene norbornene.

Vinyl norbornene can also be polymerised, making a homopolymer called polyvinyl norbornen. Like other norbornenes, this is a regioselective reaction where the double bond inside the norbornene ring polymerises and the double bond on the vinyl group outside the ring does not. The homopolymer is not commonly used, but vinyl norbornene can be used instead of ethylidene norbornene to make EPDA rubber copolymers.
