Abstract
A composition contains (A) an ethylene/α-olefin copolymer having a density from 0.855 g/cc to 0.895 g/cc and a melt viscosity, at 177° C., from 5,000 mPa-s to 50,000 mPa-s; (B) a functionalized propylene-based polymer containing from 1 wt % to 10 wt % functional groups, the functionalized propylene-based polymer having a melt viscosity, at 190° C., from greater than 10,000 mPa-s to 50,000 mPa-s and a weight average molecular weight, Mw, greater than 30,000 g/mol; (C) a tackifier; and (D) a wax.
