Adhesive compostions with wide service temperature window and use thereof

A hot melt adhesive composition consisting of:

• (A) about 10 to about 60 wt % of an ethylene vinyl acetate polymer, wherein the vinyl acetate content is less than 25 wt %;
• (B) about 2 to about 10 wt % of a functionalized metallocene catalyzed polyethylene copolymer having a viscosity range of 10,000 to 20,000 cP at 350° F., wherein the functionalized metallocene catalyzed polyethylene copolymer is grafted with a functional group selected from fumaric acid, acrylic acid, acetate, sulfonate, citaconic anhydride or maleic anhydride;
• (C) a wax;
• (D) about 20 to about 60 wt % of a tackifier;
• and
• (E) a stabilizer, plasticizer, oil, antioxidant, crosslinking agent, filler, nucleating agent, adhesion promoter, elastomer, colorant, rheology modifier or mixtures thereof,
• wherein the total wt % of the components is equal to 100 wt % of the adhesive;
• wherein the adhesive has a clear, miscible state at the molten temperature;
• and
• wherein the adhesive is characterized as having higher low temperature flexibility and higher heat resistance over an adhesive without the functionalized metallocene catalyzed polyethylene copolymer.
