Cooligomers of 1-hexene with dicyclopentadiene were synthesized. Depending on the cooligomerization conditions, cooligomers with the molecular weight of 1000–4000, containing 10–20% dicyclopentadiene units, were obtained in a 76–92% yield. Aluminum chloride was used as the cooligomerization catalyst. The cooligomers synthesized were tested as components to M-6 and I-12A petroleum oils with the view of increasing their viscosity. The use of 25–40% cooligomer in these oils allows preparation of base oils with the viscosity index of 93–126. The resultant compounded oil possesses anticorrosive properties due to the presence of the dicyclopentadiene units in the cooligomer.
