ABSTRACT:
The present invention describes a method for inhibiting the polymerization of unsaturated silanes by the addition of a non-aromatic stable free radical during any of the steps of the formation of the desired silane, the purification of the desired silane, and to the desired silanes, as well as compositions of the inhibitors and the silanes. Particular classes of silanes to be inhibited include acryloxy-, methacryloxy-, and vinyl- functional silanes. The free radicals for use as inhibitors include various nitroxides. The free radicals taught herein are effective as inhibitors at elevated temperatures, for extended periods of time, and even in the absence of molecular oxygen.
