Abstract: This invention describes novel chemical compounds whose structures are hybrids between sulfur-containing and non-sulfur-containing silanes wherein the two types of silanes are linked by siloxane bonds. The invention includes methods of preparation for the hybrid silanes as well as their use in filled rubbers as coupling agents. The hybrid silanes described are unique in that a certain amount of water in their preparation leads to superior performance in their intended application, and that they can thus be produced more efficiently and safely than coupling agents currently used in the art, from readily available hydrated raw materials.
