For this purpose, it is provided that a paste which contains finely-crystalline N,N'-bis-salicyloyl hydrazine in fine distribution in a liquid to wax-like aliphatic hydrocarbon of low volatility is worked into the polymer. The method is particularly well suited for stabilizing polyolefins for cable and wire insulation.
