Abstract: Possibility to use Stobadine dipalmitate, the antioxidant effect of which was found in search of antiarrhythmic drugs, for poly(vinyl chloride) stabilization has been studied using seventeen film samples. Degradation in real atmosphere at 180°C was followed potentiometrically and action of Stobadine dipalmitate has been evaluated. Stobadine dipalmitate in small amount (0.125 %) is able to slow down the rate of degradation in the presence of Irganox 1010, but in combination with Ca/Zn stabilizer system it was impossible to use Stobadine dipalmitate for polymer stabilization.
