실험 절차

50 g of hexamethylcyclotrisiloxane, 35.6 g of trimethylsilyl methacrylate, 2.5 g of zinc chloride and 0.4 g of 4-methoxy phenol were dissolved in 50 ml of toluene. After 11 h at 100° C., the mixture was allowed to cool until room temperature, 40 ml of triethylamine were then added and the salts were filtered. After evaporation of the solvent, distillation under reduced pressure (0.3 mbar, 80° C.) furnished pure nonamethyl-1-methacryloyloxy-tetrasiloxane.
