| Research Abstract |
Effect of shear flow on the crystallization behavior of poly(L-lactic acid)/poly(D-lactic acid) blend was investigated by means of Small-Angle and Wide-Angle X-ray scattering measurements with an aid of synchrotron radiation. In addition to the great enhancement in its crystallization rate, it was also found that stereocomplex network structure in the molten state of poly(L-lactic acid) transform into shish structure under shear flow.
