Abstract:
The present disclosure provides a composition. In an embodiment an adhesive composition is provided and includes (A) a propylene-based interpolymer having a density from 0.850 g/cc to 0.900 g/cc; (B) an ethylene-based polymer composition having a melt viscosity at 140° C. from 10 mPa*s to 1,000 mPa*s; and (C) a tackifier. The composition has a molecular weight distribution ratio from 1.00 to 1.40, wherein the molecular weight distribution ratio is the molecular weight distribution of the propylene-based interpolymer of component (A) compared to the molecular weight distribution of the ethylene-based polymer composition of component (B). The composition has a density ratio from 0.93 to 1.30, wherein the density ratio is the density of the propylene-based interpolymer of component (A) compared to the density of the ethylene-based polymer composition of component (B).
