Multilayer films that include a thermotropic liquid crystalline polymer film layer and a polypropyene film layer are bound together using hot melt adhesives which may be either (1) a blend of poly(α-olefins), comprised of isotactic polypropylene, a polymer of a second lower poly(α-olefin), and a small amount of a higher poly(α-olefin), or (2) a blend of poly(propylene-graft-maleic anhydride) and a dimer acid based polyamide. These hot melt adhesives also act as compatiblizers for blends of polypropylene and thermotropic liquid crystalline polymers. |
