ABSTRACT:
This invention relates to novel hydrocarbon resins and processes for their preparation. More particularly, the invention relates to a liquid hydrocarbon resin prepared by polymerizing norbornene and xylene with a Friedel-Crafts catalyst. The polymerized resin is hydrogenated to provide water white liquid hydrocarbon resins useful as liquid tackifiers in preparing hot-melt adhesive formulations.
