Abstract
A process for producing a hydrocarbon resin which comprises polymerizing, by means of a Friedel-Crafts catalyst, a mixture of (1) a residual fraction obtained by polymerizing a fraction of a boiling point range of from 140.degree. to 280.degree. C. obtained from the decomposition of a petroleum and containing unsaturated hydrocarbons and removing the resulting polymer and (2) phenol and/or a phenol derivative.
