Notes:
Radical copolymerization of a nitro group containing azo-dye monomer (1) and methyl methacrylate leads to significantly higher polymerization rates and higher molecular weights when dispersion technique is used instead of solution polymerization. The preparation of mechanically stable coatings and free films with good mechanical properties and transparency for electro-optical investigations is possible by a spin coating technique with the dispersion copolymers. The dye side chains of these copolymers can be poled in an electric field. The orientation of the side chains leads to a change of the light absorption in the dye absorption band. Results of m-line spectroscopy show that the copolymers possess wave guiding properties.
