Abstract

By using quantum chemical calculation method of high level B3LYP/6-31+G(d,p) assessed the reactivity of antioxidants: 2,6-di-tret-butyl-4-methylphenol, 2,2'-methylene-bis-(4,6-methyl-tretbutilfenol), 4-(N,N-dimethylaminomethylene)-2,6-ditretbutilfenol, N-(2-ethylhexyl)-N'-phenyl-1,4-phenylenediamine. It has been shown that large deformation of valence angles, increasing the length of the communication link N-(2-ethylhexyl)-N'-phenyl-1,4-phenylenediamine give rise to severe stress and, as a consequence, increasing its reactivity.
