AB  - Super-tough poly (l-lactide) (PLLA) without compromising its biodegradability and 
      biocompatibility was fabricated by reactive blending with PLLA and maleic 
      anhydride grafted starch (MS)/poly (ethylene glycol) diacrylate (PEGDA). PEGDA as 
      reactive compatibilizer exhibits higher compatibilization efficiency and 
      significant plasticization effect in PLLA matrix. Fourier transform infrared 
      spectroscopy (FT-IR) confirmed that PEGDA monomer successfully located at the 
      molecules of MS and some interesterification reactions occurred between PEGDA and 
      PLLA. The ductility of PLLA materials were significantly improved, for example, 
      the elongation of break increased to 298% at the optimum PLLA/MS/PEGDA content. 
      Dynamic mechanical thermal analysis (DMTA) demonstrated the glass transition 
      temperature of blends decreased with the contents of MS/PEGDA increasing. The 
      differential scanning calorimeter (DSC) results revealed that cold 
      crystallization temperature and melting temperature of blends were decreased with 
      the augment of the contents of MS/PEGDA. Wide angle X-ray diffraction (WARD) and 
      DSC certified that a high crystalline article was obtained through practical 
      extrusion process, which could propagate shear yielding deformation to dissipate 
      energy during tensile fracture. Scanning electron microscope (SEM) demonstrated 
      that the blends with PEGDA did not exhibit a visible phase-separated morphology 
      from cryogenic fractured surfaces compared with the blend without PEGDA.
