The synthesis and characterization of poly(acrylate)s and poly(methacrylate)s containing 4′‐substituted stilbene‐4‐carboxylic acid side groups attached by flexible spacers containing two, six, or eleven methylene groups are described. Most of the poly(methacrylate)s have nematic phases. In contrast, none of the poly(acrylate)s exhibit liquid crystalline behaviour.
