Abstract of the Disclosure SULFUR CURABLE SILICONE RUBBER Silicone rubbers can not normally be vulcanized or cured with sulfur. For this reason it has been traditionally difficult to co cure blends of silicone rubbers and diene rubbers utilizing conventional sulfur curatives. This problem has severely limited the utilization of silicone rubber/diene rubber blends in many applications. However, this difficulty can be easily overcome by utilizing in such blends the sulfur curable silicone rubbers of the present invention. These sulfur curable silicone rubbers are prepared by modifying silicone rubbers which contain pendent vinyl groups with N-chlorothio-sulfonamides.
