AbstractEffect of the two crystallization enhancement strategies, i.e. nucleation and plasticization, which are commonly used to promote polylactide (PLA) homocrystallization was investigated on the stereocomplex formation between poly(L-lactic acid) (PLLA) and poly(D-lactic acid) (PDLA). The goal was to enhance the kinetics and yield of stereocomplex formation from the melt for future applications in PLA melt processing. Blends with 5% PDLA with nucleating agent and/or plasticizer were prepared via melt-blending and characterized by differential scanning calorimetry (DSC) technique. Results suggest that combination of nucleation and plasticization is very effective in simultaneous enhancement of stereocomplex formation and homocrystallization.
