Procedure

100 g (0.34 mol) of trimethylolpropane triacrylate, 50 ml of toluene and 0.016 g of PtCl2 (C6H5CN)2 were charged into a 300-ml, 4-necked flask provided with a stirrer, a thermometer, a cooler, a dropping funnel and an air bubbler, and then the flask was heated to 60° C. After the reaction system reached 60° C., 66.5 g (0.41 mol) of triethoxysilane was dropwise added thereto over one hour, and reaction was continued at 60° C. for further 5 hours. After the end of reaction, toluene and unreacted triethoxysilane were distilled off, whereby the desired product was obtained.
