Process for producing a hydrocarbon resin

摘要

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 DEG to 280 DEG 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.
