摘要：
We have shown that bis-(2,6-di-tert-butyl-4-methylphenyl)phosphite (P-6) retards initiated oxidation and autoxidation of polypropylene. We have established that the compound P-6 destroys the hydroperoxide groups. We have determined the yield of radicals into the volume upon decomposition of tertbutyl hydroperoxide in the presence of P-6 in styrene at 343.1 K (0.011). We have observed synergism in the simultaneous inhibition of oxidation of polypropylene by P-6 and dimethyl-bis-(4-phenylaminophenoxy)silane.
