WebApr 22, 2016 · In the DSC curves of Figure 4, the upregulated melting points at 191.9 and 205.0 °C, and the emerging crystallization peak at 160.2 °C of stereocomplex PLA in the core of SCM revealed the successful formation of PLA stereocomplex microcrystals . WebThe DSC results of the annealed PLA samples are shown in Figure 6. The glass transition, cold crystallisation, and melting of the samples are clearly observed in the curves.
WebThe direct condensation of lactic acid monomers can also be used to produce PLA. This process needs to be carried out at less than 200 °C; above that temperature, the entropically favored lactide monomer is generated. This reaction generates one equivalent of water for every condensation ( esterification) step.
