Abstract
In the production of petroleum resins by polymerizing an unsaturated hydrocarbon-containing fraction having a boiling point ranging from -20.degree. to 200.degree. C. at -50.degree. to 100.degree. C., an improvement for producing light-colored clear petroleum resins which comprises using an aluminum chloride/fatty acid ester/aromatic hydrocarbon complex solution.
