It should be noted that
the WAXD profile of PLLA60/PDLA40 blend in Fig. 3(a) only shows
the characteristic peaks of stereocomplex crystallites, and the DSC
melting curve in Fig. 3(b) also shows a single peak at 229.1 C,
indicating that stereocomplex crystallites is the exclusive crystal-
line species in such a non-equimolar high-molecular-weight
PLLA60/PDLA40 blend and no homocrystallites is formed.
