Stereocomplex polylactide (scPLA) films were prepared by melt blending of poly(L-lactide) (PLLA) and poly(D-lactide) (PDLA) with and without an epoxy-based chain extender before compression molding. The obtained scPLA films were characterized through differential scanning calorimetry, X-ray diffractometry (XRD), tensile testing and dimensional stability to heat. XRD patterns revealed that all the scPLA films had only stereocomplex crystallites. The obtained results showed that the chain-extension reaction improved mechanical properties of the scPLA films, however, it suppressed stereocomplexation and heat resistance.Mahidol UniversityChemistryMaterials ScienceArticleSCOPUS10.3390/polym10111218
