Compounding polymers is widely used for the preparation of new materials. The disadvantage of this research is that the polymers are usually not compatible and the preparation of compoundswith suitable (mainly processing and physic-mechanical) properties is not performante [1]. Polyamide/polyethylene (PA/PE) composites are interesting because both components are relatively cheap, with advantageous properties, and are processable by melting [2]. The compatibilisation of binary polymer compounds can be made by the addition of graft copolymer, segments of which have physical or chemical affinity with two immiscible homopolymers [3]. In this case, polyethylene grafted with maleic anhydride (PE-g-MA) it was used. Polymer nanocomposites containing graphite have been considered as a new generation of composites materials due to their expected unique properties attributed to the high aspect ratio of the inorganic pellets [4,5]. Combined effects of graphite treatment and compatibilizer polymers (PE-g-MA) on the structure and properties of PA/PE/PE-g-MA/oxidized graphite composites were studies. The optimum formulation was used to prepare a series of nanocomposites under different technological conditions. Also, a correlation between their physic-mechanical properties and IR spectra (ATR technique) was proposed.
