A method for producing a petroleum resin, which comprises carrying out a copolymerization reaction in the presence of a cyclopentadiene type compound, a vinyl-substituted aromatic compound containing substantially no high molecular weight polymeric material and a solvent. The method allows the production of a petroleum resin and a hydrogenated petroleum resin which is reduced in the content of a high molecular weight polymeric material and has a narrow molecular weight distribution.

L'invention concerne un procédé de production d'une résine de pétrole, qui consiste à mettre en oeuvre une réaction de copolymérisation en présence d'un composé de type cyclopentadiène, d'un composé aromatique vinyl-substitué ne contenant sensiblement aucune matière polymérique de masse moléculaire élevée ou solvant. Le procédé de l'invention permet de produire une résine de pétrole et une résine de pétrole hydrogénée dont la teneur en matière polymérique de masse moléculaire élevée est réduite, et qui présente une faible répartition de la masse moléculaire.
