Procedure
5 g of hexamethylcyclotrisiloxane, 3.5 g of trimethylsilyl methacrylate and 0.3 g of Amberlyst A15 resin catalyst were stirred in 2.5 ml of toluene. After 7 h at room temperature the catalyst was filtered and the solvent evaporated under reduced pressure to furnish nonamethyl-1-methacryloyloxy-tetrasiloxane.
