Abstract
A propylene-alpha-olefin polymer that includes at least 50% by weight propylene, has a ratio of z average molecular weight (Mz) to number average molecular weight (Mw) (Mz/Mw) from greater than 20 to no greater than 50, and a ratio of Mz to weight average molecular weight (Mw) (Mz/Mw) of greater than 2.5, and exhibits a viscosity of no greater than 2,500 centipoise at 190° C., and a hot melt adhesive composition that includes the propylene-alpha-olefin polymer, a first wax consisting of a functionalized wax, and a second wax different from the first wax, the adhesive composition exhibiting a viscosity of no greater than 2,500 centipoise at 177° C.
