<p>A hydrocarbon-derived, tack enhancing, diolefin/ olefin backboned resin prepared by reacting, in the presence of an aliphatic hydrocarbon solvent and a selected catalyst, a monomer mixture comprised primarily of a diolefin/olefin mixture, of the piperylene/olefin type, and about 2 to about 12 weight percent .alpha.-methyl styrene. The resin has a particular application for us as a tackifier with styrene-isoprene-styrene block copolymers.</p> |
