Abstract:
A method of laminating a thermotropic liquid crystalline polymer film and a polyethylene film together, wherein said thermotropic liquid crystalline polymer film and said polyethylene fllm are heated under a compressive force with a hot melt adhesive between said thermotropic liquid crystalline polymer film and said polyethylene film to a temperature above the melting points of said thermotropic liquid crystalline polymer film, said polyethylene film, and said hot melt adhesive for a time sufficient to melt said hot melt adhesive and bind said polyethylene film and said thermotropic liquid crystalline polymer film to one another to yield a laminated film, wherein said hot melt adhesive is a polyolefin blend comprising isotactic polypropylene, a substantially amorphous second poly(.alpha.-olefin), and an oligomer of a third .alpha.-olefin which has at least 8 carbon atoms in the .alpha.-olefin monomer.
