Summary:This invention relates to an adhesive comprising a polymer composition comprising at least 50 mol % of one or more C3 to C40 olefins where the polymer composition has (a) a Dot T-Peel of 1 Newton or more on Kraft paper; (b) an Mw of at least 7000 to 80,000; (c) a branching index (g′) of from 0.4 to 0.90 measured at the Mz of the polymer composition; (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 composition, where the heptane insoluble fraction has branching index g′ of 0.9 or less as measured at the Mz of the polymer composition.
