Abstract
The present invention relates to a process for manufacturing a petroleum resin wherein a fraction (component A) containing an aromatic hydrocarbon obtained by cracking of petroleum and a thermally polymerized oil (component B) obtained by previously thermal-polymerizing the component A are mixed and then the mixture of the components A and B is subjected to polymerization by employing a Friedel-Crafts catalyst. It is also directed to propose a petroleum resin of a superior quality having a softening point optionally in a range of 30.degree.-120.degree. C. and various bromine value in such a manner that a mixing ratio of the components A and B is properly adjusted.
