摘要:Compositions containing p-dinitrosobenzene deposited onto a support of a chemically inert material which is solid at room temperature are provided. The composition is preferably formed by depositing p-dinitrosobenzene from a solution or by sublimation or in the course of its synthesis in the presence of one or more supports. Hydrophilic or hydrophobic silica, hydrophobicized zeolites, carbon blacks and layer silicates are examples of supports. The composition is useful in the production of adhesives, more particularly for bonding elastomers, e.g. in the polymerization or crosslinking of elastomers, and even more particularly in the bonding of rubber to metal.
