Polyolefin adhesive compositions and articles made therefrom
First Claim
1. An adhesive comprising:
- i) at least one functionalized component chosen from functionalized polymers, functionalized oligomers and beta nucleating agents; and
ii) an olefin polymer comprising 50 wt % or more of an alpha-olefin having 3 to 30 carbon atoms, 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, a heat of fusion of 1 to 70 J/g, a heptane insoluble fraction of 70 wt % or less, based upon the weight of the starting olefin polymer.

Abstract
Embodiments of the present invention relate to article comprising 1) a functionalized component, 2) tackifier, and 3) an olefin polymer comprising one or more C3 to C40 olefins, optionally one or more diolefins, and less than 5 mole % of ethylene having a Dot T-Peel of 1 Newton or more, a branching index (g′) of 0.95 or less measured at the Mz of the polymer; and an Mw of 100,000 or less; where the functional component is selected from the group consisting of functionalized polymers, functionalized oligomers and beta nucleating agents; 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.
