To the mixture was added gradually 42 g of trichlorosilane with stirring, while the temperature of the mixture was kept at 45° C. or below. After the addition, the mixture was heated to 60° C. and reaction was conducted at this temperature for 1 hour to obtain 8-methacryloyloxyoctyltrichlorosilane.
