Abstract
A process is described for the preparation of polymeric networks having superstructures, resulting from the use of liquid-crystalline, (poly)functional units, characterized in that build-up into polymers is carried out by the polymerization, polyaddition or polycondensation process within the liquid-crystalline, preferably nematic, temperature range of the (poly)functional units, having a liquid-crystalline character, used for building up the networks. Polymeric networks which are accessible by this process, and the use thereof, are also claimed.

Process for the preparation of polymeric networks having superstructures, characterized in that
- (a) functional units having a liquid-crystalline character, are, reacted with
- (b) functional, preferably polyfunctional, units, with or without a liquid-crystalline character, by the polymerization, polyaddition or polycondensation processes within the liquid-crystalline, the temperature range of the (poly)functional units having a liquid-crystalline character and used for building up the polymeric networks with build-up to form the polymer, and, are post-cured at temperatures outside the liquid-crystalline range.
