“…Compared to PLGA/PCL- b -PLLA, the PLGA/PCL- b -PDLA showed extra peaks at 12°, 20.5°, and 24.1°, showing the presence of stereocomplexation (SC) between PLLA and PDLA [ 38 , 59 ]. The XRD pattern of star-shaped PCL- b -PDLA plasticizer showed the characteristic diffraction PCL reflections as appearing at 21.7° and 23.9° [ 60 , 61 ].…”

To obtain fully degradable and super-tough poly(lactide-co-glycolide) (PLGA) blends, biodegradable star-shaped PCL-b-PDLA plasticizers were synthesized using natural originated xylitol as initiator. These plasticizers were blended with PLGA to prepare transparent thin films. Effects of added star-shaped PCL-b-PDLA plasticizers on mechanical, morphological, and thermodynamic properties of PLGA/star-shaped PCL-b-PDLA blends were investigated. The stereocomplexation strong cross-linked network between PLLA segment and PDLA segment effectively enhanced interfacial adhesion between star-shaped PCL-b-PDLA plasticizers and PLGA matrix. With only 0.5 wt% addition of star-shaped PCL-b-PDLA (Mn = 5000 g/mol), elongation at break of the PLGA blend reached approximately 248%, without any considerable sacrifice over excellent mechanical strength and modulus of PLGA.
