[en] In this work, the effect of different reactive compatibilizers on the mechanical properties and morphology of Polypropylene and Polyamide 6 blends was investigated. The blends were prepared in a counter-rotating twin screw extruder and samples for the tests were injection molded. The blends were characterized by X-Ray diffraction, mechanical properties and Scanning Electron Microscopy. X-Ray Diffraction results showed that the Polypropylene beta phase (hexagonal) was formed due to the presence of Polyamide 6. The compatibilizers considerably improved the mechanical properties of Polypropylene and Polyamide 6 blend. The addition of the compatibilizers reduced the Polyamide 6 particles average size and improved the adhesion between the Polypropylene and Polyamide 6 phases. (author)
