実験手順

Using a method analogous to Example 4, 212.7 g (1 mol) of chloromethyltriethoxysilane are reacted in the presence of 11.1 g (0.03 mol) of tri-n-butylphosphine and 0.1 g of phenothiazine with 130.4 g (1.05 mol) of potassium methacrylate at 90° C. The reaction is complete 3 hours after all the potassium methacrylate has been introduced. Work-up gives 244.7 g (93%) of methacryloxymethyltriethoxysilane having a purity of 99.2%.
