“…The thermal resistance of PLA can be improved by increasing its crystallinity and/or by increasing its glass-transition temperature. Blends with polystyrene, 9 polyamide, 10 polycarbonate, 11 polyoxymethylene, 12 and polytrimethylene terephthalate 13 have been investigated. 8 Another potential method is to blend PLA with other polymers having better thermal resistance.…”

This study examines the influence of three different minerals, that is, clay, calcium carbonate, and quartz on the physical, thermal, and mechanical properties of poly(lactic acid) (PLA)/poly(methyl methacrylate) blend. Rheological behavior and phase structure were initially studied by small-amplitude oscillatory shear rheology. Clay-and quartz-filled materials presented an increase in viscosity at low frequency associated with the presence of a yield stress. However, this behavior was not observed for calcium carbonate filled materials due to a matrix degradation effect. To elucidate this aspect, thermal stability and thermal properties were examined by thermogravimetric analysis and differential scanning calorimetry, showing that calcium carbonate promotes degradation of the PLA phase. No nucleating effect was observed in the presence of the minerals. Dynamical mechanical analysis and mechanical characterization revealed an increase of the overall softening temperature and, a reinforcing effect for clay-and quartz-based composites.

Polylactic acid (PLA)/polybutylene succinate (PBS) and the PLA/PBS/montmorillonite (MMT) composites were prepared by melt extrusion. The morphology structure, mechanical, thermal, and dynamic rheological properties of the composites were characterized, as well as foaming extrusion behavior of the composites was also studied. The results showed that MMT particles were intercalated into the PLA/PBS matrix forming an ‘intercalation’ structure. The toughness of PLA could be improved by blending with PBS. The comprehensive evaluation of mechanical properties of PLA/PBS was further improved by adding MMT. MMT could play the role of heterogeneous nucleation to improve the crystallization effect of PLA/PBS composite. The melt strength of PLA could be significantly increased by the synergies of MMT and PBS. Meanwhile, MMT could act as a compatibilizer to enhance the interfacial interaction between PLA and PBS. The synergies of PBS and MMT effectively reduced the density of PLA blend foam products, and increased their cell density, uniformity of cell size, and shape distribution.

“…First, there is a weak shift of the glass transition temperature of PPS towards lower temperatures which suggests that the components, although immiscible, present a reasonable compatibility by the interaction among polymer chains, as previously reported for PLA/PCL 28 and PLA/PTT/MBS blends. 29 Also, as stated by Denchev et al, 30 this shift in the calorimetric glass transition temperature values can be attributed to the incipient onset of transesterification reactions in the contact region between the two phases. Factor et al also propose that changes in the glass transition temperature for an apparently immiscible sample suggest that there is mixing within the domains.…”
