Abstract:
1. An adhesive comprising an olefin polymer composition comprising: a) a first amorphous polymer having a crystallinity of 5% or less, wherein crystallinity is determined according to ASTM E 794-85, prepared with a first catalyst; and b) a second crystalline polymer, differing in chemical and physical properties from the first polymer, having a crystallinity of 20% or more, wherein crystallinity is determined according to ASTM E 794-85, prepared with a second catalyst; and where the olefin polymer composition has: a) a Dot T-Peel of 1 Newton or more on Kraft paper; b) an Mw of at least 7,000 to 80,000; c) a branching index (g′) of from 0.4 to 0.90 measured at the Mz of the polymer composition; and d) a crystallinity of between 5 and 40%, wherein crystallinity is determined according to ASTM E 794-85.
