실험 절차

Into 63 parts of allyl methacrylate admixed with 0.04 part of chloroplatinic acid in the form of an isopropyl alcohol solution and heated at 60° 70° C. were added dropwise gradually 111 parts of 1,1,1,3,5,5,5-heptamethyl trisiloxane and, after completion of the dropwise addition of the silane compound, the mixture was heated at 90° C. for further 2 hours to complete the reaction. Thereafter, the reaction mixture was distilled under reduced pressure to be freed from the unreacted reactants and then filtered to give 1,1,1,3,5,5,5- heptamethyl-3-(3-methacryloxypropyl) trisiloxane, which is referred to as the compound B-1 hereinbelow, in a yield of 165 parts corresponding to 95% of the theoretical yield.
