Versuchsvorschrift
A solution of 3-aminopropyltriethoxysilane (20.0 g) in toluene (200 ml) was added to a 500 ml three neck flask equipped with magnetic stir bar, addition funnel, and nitrogen inlet. A total of 9.11 g of triethylamine was added to the solution and the solution was cooled to 0° C. in an ice bath. A total of 9.41 g of methacryloyl chloride was added dropwise to the reaction by the addition funnel at a rate such that the temperature did not exceed 5° C. The reaction was stirred overnight with gradual warming to room temperature. The reaction mixture was then washed 4 times with 200 ml of ice water, dried over magnesium sulfate and concentrated under vacuum. The yield was 38.4 percent and the reaction product was used without further purification.
