Abstract:
An extruded compounded polymer film, comprising at least one anisotropic liquid crystalline polymer; at least one isotropic polymer; and a compatibilizer that facilitates interfacial adhesion between the anisotropic and the isotropic polymers, said isotropic polymer forming a polymer matrix of the film and said anisotropic liquid crystalline polymer being essentially located in at least one lamellar layer embedded in the polymer matrix and substantially extending over a length and width of the film, the film having an oxygen transmission rate that is less than about 150 cm.sup.3 /(m.sup.2 .multidot.d.multidot.bar), determined according to ASTMD 3985 - 81, and a thickness of 10 to 100 .mu.m.
