ABSTRACT:
This invention relates to single component, hot-melt, pressure-sensitive adhesives based on propylene/higher 1-olefin copolymers containing 40-60 mole % of the higher 1-olefin. Suitable comonomers include 1-hexene through 1-decene. These new adhesives can be readily applied to substrates such as tape by means of conventional hot-melt coating equipment and thereby eliminate the solvent pollution problems associated with the application of current solvent-based pressure-sensitive adhesives. Our hot-melt coated tapes generally have pressure-sensitive adhesive properties at least equivalent to those of solvent coated pressure-sensitive tapes.
