Abstract
|
A polymeric amidine prepared by melt condensation was converted to a photosensitive polymesoion by a polymer analogous condensation reaction with methylmalonic acid. The polymeric mesoion was characterized by NMR, IR, and UV spectroscopies; SEC; and DSC. For investigation of optical properties, spin-coated films were prepared and analyzed by waveguide spectroscopy. It was found that the refractive index shows anisotropic changes and that the film thickness was reduced upon irradiation as a result of conversion to a poly-bis(-lactame) structure.
