Descripción

General description

Dicyclopentadiene(DCPD) is a dimer of cyclopentadiene composed of two unsaturated double bonds(one in the norbornene ring and one in the cyclopentene ring). DCPT is used inpolymers by itself and with other hydrocarbons. It is also employed in pharmaceuticals,elastomers, polycarbonates, and polyester resins.

Application

Dicyclopentadiene may be used:

• In the preparation of CF/p-DCPD ((carbon fiber/ poly-dicyclopentadiene) composites by VARTM (vacuum-assisted resin transfer molding) process.
• In the preparation of η⁵-cyclopentadienyltris(dimethylamido)zirconium catalyst.
• In the synthesis of cellulose – maleic anhydride– dicyclopentadiene copolymer matrix by free radical polymerization.

Features and Benefits

DCPD has the following advantages over orthophthalic andisophthalic polyesters:

• Low shrinkage
• Cost-effective
• Reduced emissions of styrene
• Fast curing in thin layers.
