A strong dependence of the rotational dynamics of the mesogenic units ( brelaxation) on the order of the mesophase was found in sidechain liquid crystal polymers. The preexponential frequency factor, f \* bΟ± , and the activation energy, E\* ab , of the b-relaxation rate both increase significantly (
