PCT No. PCT/EP92/01591 Sec. 371 Date Sep. 30, 1992 Sec. 102(e) Date Sep. 30, 1992 PCT Filed Jul. 13, 1992 PCT Pub. No. WO93/03114 PCT Pub. Date Feb. 18, 1993.The invention relates to a process for the preparation of liquid-crystalline elastomers or thermoset materials having a fixed, anisotropic network structure, characterized in that liquid-crystalline elastomers containing reactive radicals having unreacted functional groups are aligned in a first step by the action of a mechanical stress, and this alignment is fixed in a subsequent second step by linking at least some of the reactive radicals to polymer chains, and to liquid-crystalline elastomers or thermoset materials having a fixed, anisotropic network structure prepared by these processes.
