1. An adhesive comprising a polymer comprising at least 50 mol % of one or more C3 to C40 olefins where the polymer has:

  • a) a Dot T-Peel of 1 Newton or more on Kraft paper;

    b) an Mw of 10,000 to 100,000;

    c) a branching index (g′

    ) of from 0.4 to 0.98 measured at the Mz of the polymer when the polymer has an Mw of 10,000 to 60,000, or a branching index (g′

    ) of from 0.4 to 0.95 measured at the Mz of the polymer when the polymer has an Mw of 10,000 to 100,000;

    d) a heat of fusion of 1 to 70 J/g; and

    e) a heptane insoluble fraction of 70 weight % or less, based upon the weight of the polymer, where the heptane insoluble fraction has branching index g′

    of 0.9 or less as measured at the Mz of the polymer.
