実験手順

To the solvents of 60 g ethanol and 30 g PGMEA, 33.33 g TEOS, 5.71 g VTEOS and 2.40 g PTEOS monomers were individually added. While stirring a mixture of 1.13 g 0.1N nitric acid and 18.92 g water was poured, the reaction mixture was heated to reflux at 81° C. for 4 hours before cooling down. 8.84 g butanol was added to the reaction mixture and stirred at room temperature overnight. The resulting polymer was measured to have a molecular weight of Mn=1121 amu, Mw=1723 amu analyzed using the same GPC system as mentioned above.
