Zusammenfassung:	A process for manufacturing petroleum resins for adhesive thermofusible compositions, having a softening point comprised between 60 DEG and 110 DEG C., a molecular weight comprised between 700 and 1,500 and a Gardner color index less than 9, consisting in polymerizing a C5 hydrocarbon distillation cut issuing from a steam cracking of naphtha or gas-oil and containing less than 5% isoprene and less than 1% cyclopentadiene, in the presence of a Friedel-Crafts catalyst.
