Abstract
Metallic fillers are provided which are stabilized against corrosion. The metallic fillers are stabilized by treating the surface of the filler particles wtih a triazole, preferably an aromatic triazole. This may be accomplished either by pretreating the filler with a solution of the triazole, or by adding the triazole to a polymeric composition containing a metallic filler. Polymeric compositions are further provided, e.g. compositions for microwave absorption, comprising a polymeric binder, a metallic filler and a triazole.
