ABSTRACT:
A hydrocarbon resin having improved color and thermal stability is prepared from a petroleum cracking or reforming fraction containing cationically polymerizable hydrocarbons and having a boiling range of 140.degree. to 280.degree. C. The petroleum fraction is first heat-treated with an .alpha., .beta.-unsaturated dicarboxylic acid anhydride at 50.degree. to 250.degree. C., and then polymerized in the presence of a catalyst. The hydrocarbon resin is useful as a binder component in hot-melt adhesives, pressure-sensitive adhesives and thermofusible traffic paints.
