antioxidant activity of 6ppd derivatives in polyisoprene
Antioxidant activity of 6PPD derivatives in polyisoprene
Summary. The antioxidant activity of selected N,N '-substituted p -phenylenediamines derived from 6PPD in polyisoprene matrix has been studied by differential scanning calorimetry (DSC) under non-isothermal conditions. The kinetic parameters describing temperature dependence of induction period have been obtained.

Antioxidant activity of p-phenylenediamines studied by DSC
The antioxidant activity of six N,N′-substituted p-phenylenediamines in polyisoprene rubber matrix has been studied by differential scanning calorimetry (DSC) under non-isothermal conditions. A method for obtaining the parameters from non-isothermal DSC measurements, based on the dependence of the onset temperature of the oxidation peak on heating rate, is presented.

N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine (6PPD)
Antioxidants work in two different ways. In primary antioxidants (also called free-radical scavengers), antioxidative activity is implemented by the donation of an electron or hydrogen atom to a radical derivative. These antioxidants are usually hindered amines (p-Phenylene diamine, trimethyl dihydroquinolines,...
