One-step functionalization and reactive blending of polyolefin/polyamide mixtures (EPM/PA6)

The characterization of the blends by selective solvent extraction and IR and NMR analysis of the various fractions allowed to evidence the occurrence of maleate grafting on both EPM and PA6 as well as the formation of graft copolymers at the interface. The effect of the reactions on phase morphology development and thermal properties was evaluated by SEM and DSC analysis respectively in order to investigate the compatibilization extent in comparison with the conventional two-steps procedure. Besides tests about mechanical properties of samples produced by the extrusion were carried out.
