Dicyclopentadiene
Dicyclopentadiene, abbreviated DCPD, is the dimer of cyclopentadiene (CPD). In the pure state DCPD is a volatile solid with a characteristic odour. Dicyclopentadiene is coproduced in large quantities in the steam cracking of naphtha and gas oils to ethylene. In addition, it can be prepared in a Diels-Alderreaction of 2 cyclopentadiene molecules.

Description
Dicyclopentadiene, abbreviated DCPD, is a chemical compound with formula C10H12. At room temperature, it is a white crystalline solid with a camphor-like odor. Its energy density is 10,975 Wh/l. Dicyclopentadiene is coproduced in large quantities in the steam cracking of naphtha and gas oils to ethylene. The major use is in resins, particularly, unsaturated polyester resins. It is also used in inks, adhesives, and paints.
Most dicyclopentadiene is used as co-monomer in the production of synthetic resins, in particular unsaturated polyesters and synthetic rubbers, for example EPDM. Poly (DCPD), which contains some dicyclopentadiene as monomer is used in printing inks and engineering plastics.
