Petroleum resin belongs to a class of synthetic polymeric products and is derived from a mixture of linear and cyclic olefin monomers. The latter are byproducts of the cracking of natural gas, gas oil or petroleum naphtha. Dependent upon the usage, various petroleum resins are produced with different feed. In IRAN, the sources of petroleum resin feedstock are found in petrochemical complexes and composed of various reactive and no reactive aliphatic and aromatic components. In this research, first thorough investigation was done on suitable feedstock. Then polymerization was carried" out using a catalyst concentration of ] to 3 percent by weight of feed, at a temperature range of 0 - 100 C under atmospheric pressure, with a reaction time of 0.5 to 3 hours. The effect of reaction temperature, residence time, catalyst concentration, speed of mixing, etc. on the condition of reaction was studied and maximum yield was obtained. This is a first project of its kind in IRAN to produce petroleum resin.
