Zusammenfassung: | The insulation of electrical cables in which are utilized in environments likely to cause extraction of stabilizer systems is achieved through the use of compositions in which a disubstituted alkylhydroxyphenyl alkanoyl hydrazine is used as extraction resistant stabilizer for ethylene-propylene copolymer coating materials. Equivalent nomenclature for the preferred stabilizer is disubstituted di-t-butyl hydroxyhydro cinnamoyl(DTBHC) hydrozine. The DTBHC hydrazine is substantially the only stabilizer used in the stabilized compositions. |
