Improvement of poly(lactic acid)/polyamide 6 (PLA/PA6) miscibility is approached by reactive compatibilization with using different reactive agents. Specifically, compatibilizing efficiency of commercially available Joncryl ADR-4368 (Joncryl) and free-radical initiator 2,5-dimethyl-2,5-bis(tert-butylperoxy)hexane (L101) is compared to that of laboratory synthesized compatibilizers (poly(lactic acid) grafted with itaconic anhydride (PLA-g-IAH) and poly(itaconic anhydride) (PIAH) by online rheology monitoring in internal mixer and oscillatory rheometer. The change of morphology and particle-size distribution is evaluated by scanning electron microscopy (SEM), the extent of PLA-PA6 miscibility is determined by differential scanning calorimetry (DSC), and newly formed polymer phases are identified by high-resolution thermogravimetric analysis (HR-TGA) and solvent extraction in formic acid. Although Joncryl exhibits the most promising results in PLA-PA6 compatibility, other compatibilizers also exhibit specific benefits for PLA/PA6 blend or individual polymers.
