Zusammenfassung:Disclosed is a hot melt adhesive composition that includes a polymer component that includes a propylene polymer that includes greater than 50 mole % propylene and exhibiting a melt index greater than 150 grams per ten minutes at 190° C., and an ethylene copolymer exhibiting a melt index of at least 200 grams per ten minutes at 190° C. and an acid number of no greater than 2 mg KOH/g, and derived from ethylene and a co-monomer selected from the group consisting of vinyl acetate, alkyl acrylate, alkyl methacrylate, and combinations thereof, from 0% by weight to no greater than 8% by weight amorphous polyalphaolefin, and from 0% by weight to no greater than 25% by weight oil.
