ABSTRACT:
A process for preparing hydrocarbonaceous resins from C.sub.5 fractions is disclosed in which the starting hydrocarbonaceous fraction is enriched with cis-piperylene. A catalyst system is also disclosed for the formation of the resins by polymerization and the simplest catalyst is an aluminum halide. In other embodiments, the aluminum halide is used together with a second component such as a hydrocarbyl halide and/or a halide of a metal selected from Sn, Si, B, Ti, Pb, Sb, As and others. Resins having improved physico-chemical properties are obtained.
