Orientation is one of the vital factors for crystallization mediation of polymers.In 1987, Ikada first reported that a new crystal was formed with equimolar mixing poly(L-lactic acid((PLLA)/poly(D-lactic acid)(PDLA) through melt or solution blending, which was called stereo-complex (SC) crystal with Tm around 230℃ [1].Recently, Crystallization behavior of oriented PLLA/PDLA stereocomplex has caused widespread concern of some research workers [2-3].However, there are few reports concerning the difference of crystal transition between non-oriented and oriented PLLA/PDLA.
