Abstract
Highly ordered densely crosslinked liquid crystalline poly(vinyl ether ) films have been prepared by in situ photopolymerization of oriented bifunctional mesogenic vinyl ether monomers. Orientation was achieved by a simple surface treatment, using a unidirectionally rubbed polyimi de film. Polymerization from various monomer phases resulted in LC pol ymer network films with different molecular organizations. The films w ere analyzed with small-angle x-ray scattering, polarized light micros copy and infrared-dichroism measurements. It was shown that films with nematic, smectic A and smectic B structures were obtained, the latter having a very high degree of orientation.
