Crystallization behavior and mechanical properties of crosslinked plasticized poly( L-lactic acid).

The article presents a study on the crystallization behavior and mechanical properties of the crosslinked plasticized poly(L-lactic acid) or PLLA. The study used differential scanning calorimetry (DSC), wide-angle X-ray diffraction (WAXD), scanning electron microscopy (SEM) and tensile tests. Results indicated that the crystallization behaviors of both poly(ethylene glycol) or PEG and PLLA in the blends were restrained after irradiation.
