At higher processing temperature of
210 C, the formation of stereocomplex crystallites for PLLA50/
PDLA50 blend becomes less efficient, probably because the
increasing of the chain mobility is overcome by the great decrease of
the formed nucleation density, and the stereocomplex crystalliza-
tion rate decreases at low degree of supercooling; or the processing
temperature approaches the melting temperature of stereocomplex
crystallites.
