a functional organic monomer trimethylpropane triacrylate tmpta or a silicon compound the process of substituting methoxy ethanol as an organic solvent with trimethylpropane triacrylate functional organic monomer was performed using the difference in boiling point between methoxy ethanol and trimethylpropane triacrylate that is in the process methoxy ethanol was substituted with trimethylpropane triacrylate functional organic monomer by volatilizing the methoxy ethanol using the difference in boiling point therebetween subsequently organic inorganic hybrid materials were respectively prepared by substituting an organic solvent with trimethylpropane triacrylate functional organic monomer and concentrating the resulting product at the following weight ratios then the test for measuring the transmittances of the prepared organic inorganic hybrid materials to the content of silicon nanosol were carried out and the results thereof are summarized in table 1 below in this test each of the solvent free organic inorganic hybrid materials having different silica nanosol contents was applied onto a quartz substrate to a thickness of 10 u03bcm to form a film and then the transmittance of the film was measured using a uv visible spectroscopy as given in table 1 the solvent free organic inorganic hybrid materials exhibit high transmittance of 90 or more regardless of the content of silica nanosol here the content of a comparative solvent free organic inorganic hybrid material is 0 among the solvent free organic inorganic hybrid materials prepared in example 1 it was tested whether or not the solvent free organic inorganic hybrid material containing 30 of silica sol and 70 of trimethylpropane triacrylate was cracked the solvent.
