Abstract
A liquid crystal polymer film or fiber comprising polymeric liquid crystals having aligned multiple oriented mesogens and a process for preparing such a polymeric liquid crystal film or fiber comprising aligning in a multi-oriented state a nematic or smectic monomeric mesophase (liquid crystal monomer) and photopolymerizing the mesophase, are disclosed. The film or fiber may be adhered to a substrate, part of a liquid crystal display cell, or a free standing polymeric film or fiber. According to a preferred process, the mesophase is aligned in a multi-oriented state using linearly polarized light.

A process for preparing a composition in the form of a film or fiber, which process comprises aligning in a multi-oriented state a nematic or smectic monomeric mesophase and photopolymerizing the mesophase into a polymeric film or fiber having mesogens in one region aligned with their molecular axes oriented in a different direction than the mesogens aligned in at least one other region, wherein the orientation of the mesogens in at least one of the corresponding regions of the monomeric mesophase is induced by linearly polarized light.
