Description
The objective of this study was evaluate the effects of thermal ageing in dumbbell samples of nano composites using stove at 110 deg C, with air circulation at different periods of time. The clay, Cloisite 20 A, was added to HMSPP to obtain nano composites in proportion of 5 and 10 wt%. The nano composites were processed in twin screw extruder to compatibilizer the HMSPP (high melt strength polypropylene), polypropylene graft maleic anhydride (PP-g-MA) and the Cloisite 20 A The effects were evaluated by carbonyl index determination (CI), Fourier transformed infrared spectroscopy (FT-IR), differential scanning calorimetry (DSC), scanning electron microscopy (SEM). The nano composites showed intense cracks and yellowing after thermal ageing. (author)
