Sažetak
Recycling of polymers, with the aim of environmental protection and economical benefits, is important procedure, which is constantly developing. Poly(ethylene terephthalate), PET, can be successfully recycled by several methods. For example, it is very interesting to study mechanical recycling of PET through preparation of different polymer blends. Collected PET usually contains some small fraction of high-density polyethylene (HDPE) impurities. In this work physical and mechanical properties of recycled PET containing some amount of HDPE were studied. PET/HDPE polymer blends were prepared by extrusion in ratio 97/3, 95/5, 90/10 and 85/15. Then compatibilizer was prepared as EPDM/HDPE masterbatch. Furthermore, this compatibilizer was mixed with all prepared PET/HDPE blends. Mechanical properties (tensile strength, elongation at break and impact strength) and rheological property (melt flow rate, MFR) were determined for all prepared blends. Samples were further characterized by differential scanning calorimetry (DSC). Results show that EPDM compatibilizer has the significant influence on compatibility of PET/HDPE blends.
