ABSTRACT OF THE DISCLOSURE 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 to 230°C. The petroleum fraction is first heat-treated with an .alpha.,.beta.-unsaturated dicarboxylic acid anhydride at 50 to 250°C, and then polymerized in the presence of a catalyst. The hydrocarbon resin is useful as a binder conponent in hot-melt adhesives, pressure- sensitive adhesives and ther?sible traffic paints. - 1 -
