Multilayer films that include a thermotropic liquid crystalline polymer film layer and a poly(ethylene terephthalate) or polycarbonate film layer are bound together using a hot melt adhesive, which may be either (1) a blend of poly(.alpha.-olefins) that includes isotactic polypropylene, a polymer of a second lower poly(.alpha.-olefin), and a small amount of a higher poly(.alpha.-olefin); or (2) a polyamide-based hot melt adhesive.

Adhesives for making multilayer films comprising liquid crystalline

Multilayer films that include a thermotropic liquid crystalline polymer film layer and a polyethylene film layer are bound together using one of the following hot melt adhesives: ethylene-glycidyl methacrylate copolymer, ethylene-methyl acrylate-glycidyl methacrylate terpolymer, ethylene vinyl acetate copolymer, a polyolefin blend, ethylene-acrylic acid copolymer, and mixtures thereof.

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(.alpha.-olefins), comprised of isotactic polypropylene, a polymer of a second lower poly(.alpha.-olefin), and a small amount of a higher poly(.alpha.-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.
