We have performed a dielectric spectroscopy study of four homologous cyanobiphenyl polyacrylates with long side chains. The aand d-relaxation times were found to be sensitive to the sequential transformations between mesophases. The s d in the isotropic phase exhibits the characteristics that obeys
