ABSTRACT:
The invention is for a process to manufacture liquid crystal polymer films having balanced physical properties. The process includes feeding an oriented liquid crystal polymer material into a melt region formed between support membranes passing over the surface of and through an opening between heated rolls. The orientation of the liquid crystal polymer material is randomized and passed through the opening with the support membranes to form a laminated sandwich structure consisting of an unoriented liquid crystal polymer film between the support membranes. In another embodiment of the invention laminated sandwich structure is stretched to impart multiaxial orientation to the liquid crystal polymer film. The support membranes can be optionally removed to produce a film having a desirable surface finish.
