摘要: A process for manufacturing a petroleum resin is disclosed. The process comprises, polymerizing a petroleum fraction containing unsaturated hydrocarbons in the presence of Friedel-Crafts catalyst, and washing the polymerized product with water or an alkaline solution in the presence of 1-200 ppm of a polymer having a hydroxyl value of 40-120 mg KOH/g and represented by formula (I): ##STR1## wherein R.sub.1 represents a C.sub.4-16 alkyl group, each R.sub.2 individually represents H or a methyl group, each X individually represents H, an alkyl or an aminomethyl group, n is an integer of 0-8, and m is an integer of 8-20. The process can remarkably shorten the time required for the separation of oil from water after the polymerization, producing transparent, light-colored, petroleum resins with a low ash content.
