Abstract
Injection molding grade PLLA/PDLA compounds have been developed by melt blending. The article reports in particular about influence of acrylic core-shell impact modifier on crystallization behavior, thermo-mechanical properties of the compounds and injection molding cycle time. DSC results have shown formation of stereocomplex crystalline structure in compounds. Addition of impact modifier displays no influence on melting point or enthalpy of crystalline structure. Plasticization of compounds resulted in decrease of tensile properties, however impact strength has increased. Additionally a peak of maximum loading with additive was observed. Plasticizing effect due to addition of core-shell entities was confirmed by sharp increase of elongation at break. Only marginal effect on heat distortion temperature of the compounds was found. Increasing content of the toughening agent caused lowering of materials' flowability. Influence of impact modifier on resulting injection molding cycle time was insignificant.
