Abstract
Thermoplastic hydrocarbon resins are obtained by copolymerizing an isoolefin such as isobutylene with a diolefin such as piperylene in the present of a Friedel-Crafts catalyst in an inert hydrocarbon solvent. These resins have a softening point in the range from 80.degree. to 110.degree.C. and are compatible with ethylene vinyl acetate and polyethylene resins and are useful as tackifier resins or components in hot melt adhesives.
