A stabiliser combination comprising a deactivator and an oxidation inhibitor for polymers in contact with copper is described. A stabiliser combination of this type contains unsubstituted N,N'-bis-salicyloylhydrazine as deactivator and oligomeric 2,2,4-trimethyl-1,2-dihydroquinoline as oxidation inhibitor. This stabiliser combination is particularly suitable for polymers used as cable and wire insulation in high-voltage and communications technology. <IMAGE> |
