Abstract:
1. An adhesive comprising 1) functionalized component and 2) an olefin polymer comprising: 50 weight % or more of an alpha-olefin having 3 to 30 carbon atoms, and at least 50 ppm of a diene selected from the group consisting of: butadiene, pentadiene, hexadiene, heptadiene, octadiene, nonadiene, decadiene, undecadiene, dodecadiene, tridecadiene, tetradecadiene, pentadecadiene, hexadecadiene, heptadecadiene, octadecadiene, nonadecadiene, icosadiene, heneicosadiene, docosadiene, tricosadiene, tetracosadiene, pentacosadiene, hexacosadiene, heptacosadiene, octacosadiene, nonacosadiene, triacontadiene, cyclopentadiene, vinylnorbornene, norbornadiene, ethylidene norbornene, divinylbenzene, and dicyclopentadiene, where the olefin polymer has a Dot T-Peel of 1 N or more on Kraft paper, an Mw of 10,000 to 100,000, a g′ measured at the Mz of 0.95 or less and a heat of fusion of 1 to 70 J/g; where the functionalized component is selected from the group consisting of functionalized polymers, functionalized oligomers and beta nucleating agents, wherein the beta nucleating agents are materials that cause at least 5% beta crystallization of the crystallization that occurs, with a K value of 0.05 or more; and where the Gardner color of the adhesive does not change by more than 7 Gardner units when the adhesive has been heat aged at 180° C. for 48 hours as compared to the Gardner color of the unaged composition.
