In the liquid crystalline (I.c.) state the backbone of l.c‐polymers has to adapt an anisotropic conformation that is consistent with the I.c.‐phase structure. For macroscopically uniformly aligned samples this anisotropic backbone conformation can be obtained by applying a suitable mechanical field on chemically crosslinked I.c‐polymers. Introducing the network anisotropy a priori by synthesis, stable macroscopically aligned I.c.‐networks can be realized. We have called these networks Liquid Single Crystal Elastomers (LSCE) because their physical properties resemble that of organic or inorganic single crystals.
