ABSTRACT
Thermal stability of polymer nanocomposites prepared by melt mixing of polypropylene (PP) with organo-modified clay (Cloisite C93A) and maleic anhydride grafted polypropylene (PP-g-MA) used as compatibilizer, has been studied. Thermogravimetric analysis (TGA/DTG) results showed improved thermal stability of PP in the presence of organo-clay in oxygen atmosphere. Significant prolongation of oxidation induction time (measured at 200oC) for nanocomposite, in the presence of even 1% organo-modified clay has been found.
