  • Publication number: 20190194500
    Abstract: Ionizing radiation crosslinkable pressure sensitive adhesive precursors containing hydrocarbon tackifiers and having an acid content of no more than 3% by weight. The precursors can be exposed to a source of ionizing radiation, for example, one or both of an electron beam or gamma radiation, for an exposure time sufficient to receive an energy dose sufficient to at least partially crosslink the adhesive precursor, thereby forming a pressure sensitive adhesive. Methods of using ionizing radiation to crosslink a crosslinkable pressure sensitive adhesive precursor are also disclosed.
