実験手順

Into a reaction vessel equipped with a stirrer, thermometer and dropping funnel were placed 0.3 mole (104.4 g) of 4,4'-(perfluoroisopropylidene)dicyclohexanol, 1 mole (101.2 g) of triethylamine and 700 ml of tetrahydrofuran. To the mixture was added dropwise 1 mole (104.5 g) of methacryloyl chloride while cooling the mixture with ice. The mixture was maintained at a temperature below 20° C. for 8 hours with stirring. The reaction mixture was poured into a large excess amount of water and the resulting precipitates were recovered and washed with methanol to obtain 69 g of 4,4'-(perfluoroisopropylidene)dicyclohexanol dimethacrylate in the form of white solid.
