TI - Structure and crystallization kinetics of poly(L4actic acid) N2 - A structural investigation is described of poly(L-lactic acid)by best fitting of powder X-ray diffraction patterns. The examined sample shows the already known pseudo-orthorhombic aform, and it was possible to determine the location of the two 10, polymeric helices in the unit cell and the size distribution of the crystallites. Furthermore, a study is reported of the crystallization kinetics of the above cited polymer by light depolarization measurements in an optical microscope. The crystallization kinetic constants in bulk were evaluated in a temperature range (70- 165 "C)wider than that previously resulting from measurements of radial growth of spherulites UR - https://drive.google.com/file/d/1w8sKbRHAorJw6AWfmTjLGVgSJrvbxH-2/view?usp=drivesdk ER -
