Effect of Recycled Poly(propylene) on the Properties of a Clay Nanocomposite

Abstract

Summary: Polyamide (PA6) and poly(propylene) (PP) blends offer a good opportunity for the development of materials with new properties when they are made compatible, because they combine the thermomechanical properties of the PA6 and the easy processing of poly(propylene). [1][2][3][4][5] Moreover, in recent years has successfully managed to synthesize various types of composites based on clay with a polymer matrix. The aim of this work has been the incorporation of the clay in PA and PP blends to study the effect of its incorporation to establish a correlation between the morphology of the blends with the thermal and mechanical properties. To improve the incompatibility between the PA and the PP has been necessary to introduce a graft poly(propylene) -maleic anhydride compatibilizer (PP-g-AM). [6][7][8] In addition we have studied the incorporation of recycled PP in the system and the results were similar to those obtained with non-recycled poly(propylene).
