1. An adhesive comprising a polymer comprising at least 50 mol % of one or more C3 to C40 olefins where the polymers 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 0.98 or less 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 0.95 or less measured at the Mz of the polymer when the polymer has an Mw of 10,000 to 100,000;
d) an amorphous content of at least 50%; and
e) a crystallinity of at least 5%,
wherein the SEC graph of the polymer is bi- or multi-modal.
