Abstract
This invention relates to improved processes for hydrocarbon resin preparation. More particularly, the invention relates to treating the C.sub.5 and higher mixed thermally soaked hydrocarbon fraction mixture obtained in the steam cracking of propane and ethane with alumina prior to polymerizing the hydrocarbon fraction mixture with a Friedel-Crafts catalyst to form a high softening point hydrocarbon resin. The polymerized resin is then quenched or diluted, washed to remove catalyst residues, dried and hydrogenated to provide high softening point hydrocarbon resins.
