Observation of the conformation and structure of some liquid‐crystal polymers by small‐angle neutron scattering

Abstract

Abstract The conformation of the backbone and the structure of the mesogenic groups of some liquidcrystal polymethacrylates and polysiloxanes were determined by small‐ and low‐angle scattering of neutrons. A strong magnetic field aligned the mesomorphic monodomains. For most samples and phases the polymer backbone adopts an oblate shape versus the mesogenic director. The observation of several diffuse spots together with Bragg peaks allows to propose models for the structure of these samples.
