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