ABSTRACT
The research was conducted research into the use of commercial antioxidants Irganox 1010 (wingstay) to inhibit the oxidative degradation of cyclic polymers of natural rubber and polypropylene nanocomposite with commercial montmorillonite (PP / MMT-Clay). Proces mixing nanocomposit PP/MMT using commercial compatibiliser PP-g-MA (PB3200) made in an internal mixer at a temperature of 180 C for 10 minutes and 65 rpm rotor speed. Hyndered phenol antioxidant effectiveness was analyzed using Fourier Transform Infra Red (FTIR). Analysis of infrared is done by measuring the broad index absorption of the carbonyl group (>C=O) at a wavelength of 1700 cm-1 and a broad index uptake hydroxyl group at a wavelength of 3400 cm-1 before and after heated in an oven temperature of 125oC with variations in exposure time. The results indicate the use of antioxidant Irganox 1010 in nanocomposite PP / MMT with a stabilizing factor of 5.5. Further commercial antioxidants will be used to restrain the rate of oxidation degradation of the natural rubber products cyclical (CNR).
