1. An adhesive composition comprising:
(a) a polymer blend comprising
a first propylene-based polymer, wherein the first propylene-based polymer is a homopolymer of propylene or a copolymer of propylene and ethylene or a C4 to C10 alpha-olefin; a second propylene-based polymer, wherein the second propylene-based polymer is a homopolymer of propylene or a copolymer of propylene and ethylene or a C4 to C10 alpha-olefin; wherein the second propylene-based polymer is different than the first propylene-based polymer;wherein the polymer blend is present in the amount of about 65 wt % or more based on the adhesive composition;wherein the polymer blend has a melt viscosity, measured at 190° C. of about 900 to about 19,000 cP; and (b) a polar polyethylene component selected from at least one of an oxidized high density polyethylene wax, a silane-modified polyethylene, ethylene vinyl acetate, ethylene acrylate, organic acid-modified polyethylene, and combinations thereof. |
