POLYETHYLENE INSULATION COMPOSITION |
摘要 |
A polyolefin composition having improved oxidative stability is provided. the stabilized composition comprises an ethylene homopolymer or copolymer with a divalent metal-containing hindered phenolic antioxidant and metal deactivator having one or more hindered phenol groups linked to a hydrazo or ozamido group. The stabilized polyolefin composition is useful in the insulation of wire and cable and are characterized by increased resistance to oxidation. The composition also retains a high degree of oxidative stability upon exposure to water-blocking cable fillers. A preferred embodiment of the composition includes a third stabilizer of the compound pentaerythirtyl tetrakis ¢3(3',5'-di-t-butyl-4'hydroxyphenyl) propionate!.
