Abstract
An apparatus and method for making thermotropic liquid crystalline polymer films with improved transverse direction properties comprises two preferably embossed rollers which oscillate oppositely with respect to each along their respective rotational axes. Film made by passing a liquid crystalline polymer between such rolls has improved transverse direction properties. Such films are useful in multilayer containers and for circuit boards.
