Abstract

In this study, polymeric blends of polylactide (PLA), high density polyethylene (PE-HD) and low density polyethylene (PE-LD) in different ratios were prepared. Blending of polymers with an extruder and a kneader was performed. Mechanical, thermal, and morphological properties of the prepared blends were determined.
The results of mechanical testing showed that the addition of polyethylene (PE-LD and PE-HD) to pure polylactide significantly changed the mechanical properties of the material. The analysis performed on the scanning electron microscope (SEM) and the differential scanning calorimeter (DSC) showed that the investigated polymers were immiscible. The investigated polymer blends were partially biodegradable, while material price decreased compared to pure polylactide.
