摘要：

Small Angle Neutron Scattering experiments were carried out on liquid crystalline << side-on fixed >> polyacrylates : we observe that the polymer backbone adopts a prolate conformation in the nematic phase. Such anisotropy of the global backbone is larger for smaller spacer length. In every case we measure at low temperatures a large chain extension as previously described in polysiloxanes.
