To further investigate the compatibility of PLA/PPC blends,the Tg data were collected by differential scanning calorimetry(DSC).Figure 2 shows the DSC traces of PLA/PPC blends and the corresponding thermal parameters are given in Table 1.For pure PLA and PPC,the Tg value was about 60 and 36°C,respectively.However,two Tgs were observed in the PLA/PPC blends with different weight ratios.For example,in PLA/PPC 60/40 blend,the Tg at high temperature corresponding to the Tg of PLA was 57°C,which was 3°C lower than that of neat PLA.In PLA/PPC 80/20blend,Tg at low temperature corresponding to that of PPC was 38°C,which was 2°C higher than that of neat PPC.The Tg shifting towards each other in the blends suggests that PLA/PPC blends were a partially compatible system,which is in agreement with the results of FTIR shown in Fig.1.This partial compatibility can be attributed to their similar chemical structures of the two polymers.
