In isothermal crystallization from the melt, only stereocomplex crystallites as a crystalline species were formed in all the blends at crystallization temperature above 130 degrees C. The spherulite growth rate and crystallinity values decreased monotonically with deviation of the PDLA content from 50. Surprisingly regime analysis revealed that the crystallization mechanism of the blends was independent of PDLA content. In non-isothermal crystallization of melt-quenched specimens during heating, the cold crystallization of blends takes place rapidly at a lower temperature compared to that of pure PLLA and PDLA. This is attributable to the rapid stereocomplex crystallization or the nucleating effect of stereocomplex crystallites formed during quenching from the melt or second heating.
