Hot Melt Adhesive With Functionalized Metallocene Catalyzed Polyolefins

A hot melt adhesive composition, comprising a blend of the following components:

• about 5% to about 50% by weight of a functionalized polymer comprising a metallocene catalyzed random polyolefin elastomer grafted with maleic anhydride;
• about 5% to about 70% by weight of a non-functionalized polymer comprising a metallocene catalyzed random or block polyolefin elastomer as a secondary polymer with melt index equal or greater than 15 MI;
• about 0% to about 30% by weight of solid or liquid plasticizer;
• about 5% to about 30% by weight of a wax;
• about 20% to about 70% by weight of a first tackifying resin having a softening point of at least about 95° C.;
• about 0% to about 20% by weight of an aromatic reinforcing resin having a softening point equal to or higher than 115° C.;
• about 0.1% to about 5% by weight of a stabilizer;
• and
• about 0% to about 3% by weight of auxilliary additives;
• wherein the components total 100% by weight of the composition, and the viscosity of the composition is equal to or less than about 20,000 centipoise at 163° C.
