We report a short outline of chain‐conformation informations obtained by small angle neutron scattering (SANS) studies of different kinds of Liquid Crystalline Polymers (LCPs). We conclude that in the nematic phase the prolate shape of the chains are directly connected to the orientational order and the magnitude of the chain extension strongly depends on molecular parameters relative to the coupling mesogen‐chain. The behavior is markedly different when the backbone anisotropy is oblate shape due to the chain confinement between the smectic layers.
