Multilayer laminates including films, sheets, preforms, containers and other articles having at least one wholly aromatic, amorphous, stretchable liquid crystalline polymer layer with at least one non-polyester thermoplastic polymer layer are provided as well as methods for producing and stretching the multilayer articles. The laminates are suitable for thermoforming and stretch blow molding applications and may be stretched at temperatures lower than the molten state of the liquid crystal polymer and at high total draw ratios without fractures or tears. Containers suitable for food or beverage products may be produced from the laminates.

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.

A thermally expandable wax composition and its use in polymer-based actuators is disclosed and claimed. The compositions are wax-based and include conductive filler as well as a viscosity modifier to stabilize the composition against segregation. Optionally included are thermoxidative stabilizers.

The invention relates to multiple fiber connectors for thermoplastic optical couplers and fibers. The multiple-fiber connectors facilitate the connection of optical fibers to a star coupler and provide low levels of light loss between input/output ports of a coupler. The invention further relates to a terminator hot plate apparatus for the semiautomatic termination of optical fiber ends, and a new cladding material for thermoplastic optical couplers and fibers.

A unitary injection molded waveguiding optical element is disclosed and claimed. In a preferred embodiment, there is shown an NXN star coupler 310 with a plurality of fibers 314, 316 integrally formed with the mixing body. Preferably, the fibers are continuously transitioned to the signal mixing body such that the optical path is substantially constant and the surfaces are free from lateral discontinuities.

An optical fiber bundle 10 is disclosed including a plurality of polymer optical fibers 12 disposed within a rigid sleeve 14. The fibers have been drawn to a draw ratio of at least 1:1.5 prior to placing them within the sleeve, whereupon the structure 13 is heated to induce elastic relaxation of the fibers which contract in length and expand in girth. The expansion within the rigid sleeve results in a close-packed geometry.
