ABSTRACT:
The condensation products of oxalyl dihydrazide and 3,5-di-tertiary-butyl-4-hydroxy aryl carbonyl compounds are found to stabilize polyethylene against oxidative degradation. Stabilizer effectiveness is retained with the polymer in contact with copper. Stabilized polymers are effectively utilized as wire insulation.
