Summary The morphological stability and the mechanical properties of postconsumer polyethylene terephthalate (PET) and high density polyethylene (HDPE), at different composition with and without compatibilizer were investigated. The blends were prepared in an internal mixer and in a twin screw-extruder at different stretching ratio. For uncompatibilized blends, (previously prepared by extrusion), the particle size of the dispersed phase increases after being reprocessed in an internal mixer. However, in the case of compatibilized blend the particle size remains constant. Consequently, the compatibilizer reduces interfacial mobility, coalescence effects and stabilizes the morphology. The mechanical properties are also modified by the presence of the compatibilizer, mainly the elongation at break.
