The goal of the investigations was to measure the dynamics of molecular reorientation in polybutadiene backbone based polymer grafted with photochromic thiols. Measurements were performed in a typical degenerate two- and four-wave mixing experiments, in which time constants of dynamic diffraction grating formation were determined. Holographic gratings which were inscribed in polymeric liquid crystalline films show switching times (build-up and decay) within the 20–70 ms range.
