Abstract

We report on the first high-resolution x-ray measurements of a second-order nematic to (bilayer) smectic-A phase transition in a polymeric liquid crystal, P4.1 polysiloxane. The critical exponents of the parallel and perpendicular correlation lengths and susceptibility were N=0.77±N0.05, N=0.57±N 0.08, and =1.33±N0.10, respectively. The bare correlation lengths, N 0q0 and N0q0, were 3.27 ±N 0.08 and 1.09 ±N 0.14, respectively, and are unusually large in comparison to monomeric liquid crystals.
