Abstract:
An aromatic modified aliphatic hydrocarbon resin, characterized in that the resin has a Ring and Ball (R&B) softening point of 94.degree. C. or lower, a weight-average molecular weight M.sub.w of not more than 2000 Dalton, a Z-average molecular weight (M.sub.z) of not more than 6000 Dalton and a mixed methylcyclohexane aniline cloud point (MMAP) between 25 and 45.degree. C. andfurther characterized in that the resin is obtained by subjecting a polymerization feed comprising a petroleum feed to a Friedel-Crafts polymerization wherein said petroleum feed comprises (a) C5 and C6 olefins and/or diolefins including cycloolefins in an amount of 45 wt % +/-25 wt % of the petroleum feed, (b) aromatic monomers in an amount 40 wt % +/-20 wt % of the petroleum feed, and (c) (di-)cyclodiolefins in an amount of 20 wt % +/-10-wt % of the petroleum feed.
