✦ Synopsis

Inorganic-organic hybrids have been synthesized by incorporation of the inorganic component of Ti(OCzHs)d into the organic polymer of ethyl cellulose. The inorganic-organic hybrids did not dissolve in toluene used as a solvent for the starting materials. The ethanol was formed as a by-product of the alcoholysis condensation reaction between Ti(OCzH& and ethyl cellulose. These results suggest that ethoxy groups of Ti(OC2H5)4 react with hydroxy groups of ethyl cellulose to form cross-linking bonds of -0-Ti-O-.

The reaction of Ti(OCzH5)4 with ethyl cellulose was further investigated by Fourier transform infrared (FT-IR) spectroscopy. The FI-IR spectroscopic experiments revealed that the Ti-0 bond state of Ti(OCzH& was changed by refluxing a toluene solution of Ti(OC2H5)4 with ethyl cellulose. The inorganic-organic hybrids have an interesting dielectric property; their dielectric constant is higher than that of ethyl cellulose and that of a simple mixture of TiO;! and ethyl cellulose.
