Adhesives comprising one or more tackifiers, ethylene vinyl acetate copolymers ("EVA") and a low viscosity, low number average molecular weight (Mn between 700 and less than 1000) ethylene/alpha-olefin interpolymer which has wax-like properties, and produced using a single metallocene catalyst system, were formulated, and have adhesive characteristics over a broad temperature range. These hot melt adhesive compositions ("HMAs") have properties comparable to those of commercially available, three component HMAs comprising ethylene vinyl acetate polymers, tackifÊer and wax. HMA embodiments include those wherein the ethylene/alpha-olefin interpolymers comprise ethylene and propylene as copolymers, and the interpolymer has a low Brookfield viscosity, between 20 - 50 centipoise at 300°F.
