Abstract

Described herein is an absorbent article. The absorbent article includes an assembly of components and an adhesive composition joining at least two of the assembly of components together. The adhesive composition includes from about 50 wt. % to about 80 wt. % of one or more copolymers and a blend of one or more heterophase copolymers. The one or more copolymers include from about 30 mole % to about 70 mole % of monomer units selected from ethylene. 1-butene, and mixtures thereof. The one or more copolymers also include from about 30 mole % to about 70 mole % of propene monomer units. The adhesive composition is free of polyisobutylene and has a viscosity of from about 2,000 mPa·s to about 11,500 mPa·s at 150° C.
