Sažetak
Poly(vinyl alcohol) (PVA) and poly(ethylene) oxide (PEO) are widely used water-soluble and biodegradable polymers that possesses high biocompatibility. In this work PVA/PEO blends were prepared via solution casting method, where the solvent was water. After drying, samples were characterized by differential scanning calorimetry (DSC) and thermogravimetric analysis (TG). Based on the results of the DSC analysis, the specific thermal trasitions were determined. Since the possible intermolecular interaction between PVA and PEO could not be confirmed by DSC, infrared spectroscopy with Fourier transform (FT-IR) was utilized. Finally, the TG analysis revealed a three-stage degradation pattern in the case of all PVA/PEO blends, similar as neat PVA. On the other hand, neat PEO exhibited only a single stage degradation pattern confirming its superior thermal stability to PVA.
