Abstract
A hot melt adhesive composition includes at least a semi-crystalline copolymer of propylene and a polyethylene wax having a Brookfield viscosity of about 20 cP to 500 cP at 140° C., a density of about 0.95 g/cm3 to 0.99 g/cm3 between 23° C. and 25° C., and a Mettler drop point of about 110° C. to 135° C., wherein the composition is characterized by a effective set time of about 0.1 second to 5 seconds. Articles including the composition and methods of making articles including the composition are described.
