Abstract: The effect of concentration of a ternary mixture of antioxidants DPPH—PBN—PT on the oxidation of extracted natural rubber was investigated.
At the equimolar ratio, a strengthened inhibitory effect of the mixture was
observed with respect to the additivity of individual components or binary
mixtures of the antioxidants DPPH—PBN and DPPH-PT. The course
of the observed induction periods as a function of concentration of the
original mixture is similar to that of additive induction periods. I t was confirmed that DPPH is a synergistic component of the ternary inhibitory system.
