چکیده انگلیسی
The crystallization behavior of poly(d-lactide) loaded with xylan propionate (XylPr) and xylan butyrate (XylBu) was investigated. Non-isothermal crystallization study revealed that the crystallization temperature (Tc) of PDLA decreased by almost 30 °C when loaded with 1% XylPr or XylBu. PDLA blends containing 0.1% xylan ester produced similar results. Isothermal crystallization study suggests faster rate of crystallization of the PDLA blends as indicated by their t1/2 values. The Xc values of the PDLA blends were also higher as compared to neat PDLA. However, the PDLA blends still possessed lower degrees of haze due to the presence of smaller spherulites. Based on TMA, PDLA blends exhibited better thermal stability than neat PDLA.
