Dicyclopentadiene (DCPD)

Dicyclopentadiene (DCPD), the dimer of cyclopentadiene (CPD), is synthesized through a Diels-Alder addition reaction. These DCPD compounds stem from the high-temperature breakdown of petroleum fractions and are identified as exceptionally reactive intermediates. They find extensive application in various resin types such as aromatic hydrocarbons, unsaturated polyesters, phenolics, and epoxies.
