Two diaromatic diepoxides 4-(2,3-epoxypropoxy)phenyl-4-(2,3-epoxypropoxy)-benzoate (1) and 4-(2,3-epoxypropoxy)-benzylidene-4-(2,3-epoxypropoxy)-aniline (2) have been synthesized and their mesogenic properties have been studied. 1 and 2 were reacted with 4,4＇-diaminobiphenyl (3), 4-aminophenyl-4-amino benzoate (4), 4,4＇-diaminodiphenylmethane (5), and 2,4-diaminotoluene (6) to investigate the formation of anisotropic networks and to prove the results obtained with model compounds. The influence of the mesogenic properties of epoxides and diamines, the type of oligomers formed, curing temperature, vitrification and annealing at constant conversion on the formation of a liquid crystalline network was studied.
