This study aims to improve the ductility of poly (lactic acid) (PLA). For that purpose, bioblends based on PLA and epoxidized vegetable oils (EVO) as bioplasticizers were prepared. Commercial sun ower oil was epoxidized and epoxidized sun ower oil (ESO) was used as plasticizer for PLA. To investigate ESO potential as plasticizer for PLA, its plasticizing effect was compared with commercial epoxidized soya bean oil (ESBO). The plasticizers (ESO or ESBO) were respectively compounded with PLA at 10, 20, 30, and 40 wt%. Mechanical (tensile and Shore D hardness), thermal (differential scanning calorimetry (DSC), thermogravimetric analysis (TGA)) and morphological properties (optical microscopy and scanning electron microscopy (SEM)) were characterized. The results showed that the addition of ESO or ESBO to PLA decreased tensile strength and tensile modulus compared to neat PLA but increased elongation at break for which an optimum (9.02%, 15.55% and 33.67% for ESBO, ESO 5.5% and ESO 6.5% respectively) was reached at a content of 20 wt% of plasticizer. The structures of the obtained plasticized PLA were con rmed by FTIR spectroscopy. DSC showed a clear decrease in the glass transition temperature of PLA and SEM analysis proved successful modi cation on the PLA brittle morphology with addition of EVO. On the other hand, TGA results revealed signi cant increase in the thermal stability. Based on the results of this study, ESO exhibited promising results regarding

The goal of this research is to see how the amount and particle size of calcium carbonate (CaCO 3 ) used in the foamed layer in use for PVC-coated textiles affects the thermal properties of the material. Two different particle sizes were used at various concentrations. The impact of different CaCO 3 loadings and particle sizes on the PVC foamed layer’s thermal properties were examined. Thermogravimetry (TGA and DTG) and differential scanning calorimetry (DSC) measurements were utilized to investigate the thermal properties of the PVC foamed layer and the samples have been also characterized by FTIR spectroscopy. According to the findings, the thermal stability of the foamed layer was improved with the addition of calcium carbonate. Through the higher surface area between the filler and the PVC matrix, smaller particle sizes have produced the best results. The PVC foamed layer shows also changes in FTIR spectra after adding CaCO 3 , and the intensity of peaks increases with decreasing CaCO 3 particle size.
