CAS number 77-73-6
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.
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.
