To verify the correctness of this hypothesis, we conducted experiments on the inhibition of the oxidation of polj ropylene by a mixture of two antioxidants - 2,2-methylene-bis-(4-methyl-6-tert-butylphenol) (I) and 2,6-di-(l,l-dimethylhexyl)paracresol (II). When impurities of the two antioxidants are present in concentrations x and X2, the increase in the concentration of active centers n as against equation (23) is described in the equation...
