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 laminate formed from a substantially stretched non-molten wholly aromatic liquid crystalline polymer and non-polyester thermoplastic polymer

A stretchable liquid crystal polymer having recurring units derived from p-hydroxybenzoic acid, 6-hydroxy-2-naphthoic acid, at least one aromatic diacid and at least one aromatic diol and/or hydroxyamine component, at least a portion of which is 4,4&prime;-biphenol, and one or more aromatic monomers that provide the polymers with selected 1,3-(meta-) linkages. Stretchable polymers are especially suitable for multilayer laminates and bicomponent fibers.

Stretchable polymers and shaped articles produced by same

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-liquid crystalline thermoplastic polyester 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 to at least 100 percent elongation at temperatures below 200&deg; C. and at high total draw ratios without fractures or tears. Containers suitable for food or beverage products may be produced from the laminates.

Process for producing highly stretchable, amorphous anisotropic melt-forming polymers having recurring units derived from p-hydroxybenzoic acid, 6-hydroxy-2-naphthoic acid, at least one aromatic diacid and at least one aromatic diol and/or hydroxyamine component, at least a portion of which is 4,4&prime;-biphenol, which process comprises incorporating into such polymers recurring units derived from one or more aromatic monomers that provide the polymers with selected meta-linkages wherein each of said recurring units is present in the polymer in specific amounts.

Process for producing amorphous anisotropic melt-forming polymers having a high degree of stretchability

Process for producing highly stretchable, amorphous anisotropic melt-forming polymers having recurring units derived from p-hydroxybenzoic acid, 6-hydroxy-2-naphthoic acid, at least one aromatic diacid and an aromatic diol and/or hydroxyamine component, at least a portion of which is 4,4'-biphenol, which comprises incorporating into such polymers recurring units derived from resorcinol and at least one additional monomer that provides the resulting polymer with selected meta linkages, wherein each of said recurring units is present in the polymer in specified amounts.

Process for producing amorphous anisotrophic melt-forming polymers

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.

The present invention relates to monoanhydride monomer compounds, methods of making such compounds and reaction products of the monoanhydride-diacid compounds with other monomers. The inventive monomer compounds exhibit selective reactivity, that is, the dianhydride locus is substantially more reactive towards amines than the diacid locus making it possible to sequentially synthesize a new class of materials suitable for membranes, catalytic substrates or any speciality material required for advanced applications.
