Dicyclopentadiene has many unsaturated double bonds and is very active in chemical reaction. It can react with many kinds of compounds to produce many kinds of derivatives. It can be used in ethylene propylene rubber, unsaturated polyester, synthetic petroleum resin, coating resin, synthetic resins, synthetic perfumes, organic chemical intermediates and other production, dicyclopentadiene can also be depolymerized to cyclopentadiene, cyclopentadiene is a synthetic resin, pesticides, cyclopentadiene, and dicyclopentadiene (DCPD) are the main intermediates of cyclopentadiene. It is widely used in auto parts and industrial parts. It has good weather resistance, aging resistance, acid resistance, heat resistance, chemical resistance and so on. It can be obtained by copolymerization of dicyclopentadiene with ethylene and propylene.

At present, the third monomer of industrial ethylene propylene rubber mainly dicyclopentadiene, ethylidene norbornene, 1,4-hexadiene. Among them, ethylidene norbornene to cure speed, high yield, less secondary reactions and the most widely used. Ethylidene norbornene can be dicyclopentadiene and 1,3-butadiene reaction, and then by isomerization obtained. In addition, dicyclopentadiene and cyclopentadiene copolymerization, available mechanical strength, with natural rubber comparable to the general rubber. This product has been in the United States, Japan, Germany into the industrial development stage. Dicyclopentadiene by the thermal polymerization can be used for coatings, pressure-sensitive adhesives, hot-melt adhesives, printing inks and other fields of petroleum resin; dicyclopentadiene prepared by the adamantane drug treatment of influenza A is a cure; Hydrogenated from dicyclopentadiene hydrogenated in the system and its derivatives can be used as high energy racing, missile high-performance, high-density, high calorific value fuel; in dicyclopentadiene by adding catalyst and activator, can be made with excellent mechanical properties, the shape of the RIM complex products; Dicyclopentadiene and a variety of alcohol reaction, can produce a series of ether or ester products, the synthesis of fragrances elegant fragrance; cobalt carbonyl or rhodium in the role of catalyst, Dicyclopentadiene and carbon monoxide carbonyl reaction generated dialdehyde, and then further hydrogenation of polyols can be used as plasticizers; Dicyclopentadiene can also be with metal elements (such as iron, nickel, cobalt, etc.) to form a comparison stable metal organic compounds, such as ferrocene, not only in the fuel use, energy saving smoke, but also can be used as UV absorbers, ammonia catalyst, wear-resistant materials accelerator. In addition, dicyclopentadiene can also be used for tung oil, linseed oil, soybean oil, fish oil and other modified to accelerate its drying, improve water resistance, alkali resistance. Another potential demand of Dicyclopentadiene is unsaturated polyester resin, which can replace phthalic anhydride production of various grades of polyester resin.
