ABSTRACT:
A process for preparing a hydrogenated hydrocarbon resin is provided which comprises the steps of: (A) polymerizing 100 parts by weight of a hydrocarbon mixture containing fractions of cracked oils obtained by cracking of petroleum and having boiling points ranging within from 140.degree. to 280.degree. C., said polymerization being effected in the presence of 0.1 to 3.0 parts by weight of a phenol and 0.01 to 5.0 parts by weight of a Friedel-Crafts catalyst at - (minus) 30.degree. C. to + (plus) 60.degree. C. to obtain a polymerized hydrocarbon mixture; (B) adding 0.1 to 20 parts by weight of a basic substance to 100 parts by weight of said polymerized hydrocarbon mixture, to neutralize said polymerized hydrocarbon mixture at 10.degree. to 100.degree. C.; (C) further adding an activated clay in an amount of 0.1 to 20 parts by weight based on 100 parts by weight of said polymerized hydrocarbon mixture, to treat said neutralized hydrocarbon mixture with said activated clay at 10.degree. to 100.degree. C.; and (D) hydrogenating said hydrocarbon mixture treated with said activated clay.
