Abstract:
1. A film comprising a polymer composition that includes a thermotropic liquid crystalline polymer, wherein the polymer composition has a melt viscosity of from about 35 to about 500 Pa-s, as determined in accordance with ISO Test No. 11443 at 15° C. higher than the melting temperature of the composition and at a shear rate of 400 seconds −1 , and wherein the composition exhibits a maximum engineering stress of from about 340 kPa to about 600 kPa, as determined at the melting temperature of the composition with an extensional viscosity fixture and a rotational rheometer, and further wherein the melting temperature of the composition is from about 300° C. to about 400° C.
