ABSTRACT:
The condensation product of oxalyl dihydrazide and 3,5-di-tertiary-butyl-4-hydroxy aryl carbonyl compounds is 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.
