ABSTRACT:
A process for preparing a hydrocarbon resin which comprises copolymerizing (A) a hydrocarbon fraction boiling within the range of 130.degree. to 300.degree. C. obtained by cracking, reforming and/or refining petroleum with (B) dicyclopentadiene in the presence of a Friedel-Crafts catalyst in a proportion such that the resulting hydrocarbon resin contains, based on the total weight thereof, 20 to 80% of a unit derived from the dicyclopentadiene (B).
A hydrocarbon resin having a number average molecular weight of 300 to 2500, a softening point of 40.degree. to 180.degree. C., a bromine number of 5 to 100 g/100 g, and a Gardner color hue of 5 to 17, prepared by the above process. This hydrocarbon resin is useful as an adhesive component of pressure-sensitive adhesives and hot-melt composition.
