Recently, stereocomplex-type polylactide (SC-PLA) has generated growing interest because the unique SC crystals can provide drastic improvement in the heat/chemical resistances and durability of bio-derived and biodegradable PLA, exhibiting great potential to compete with some petroleum-derived engineering plastics in diverse applications. However, SC-PLA suffers from poor melt memory effect as well as significant thermal degradation after being completely melted at temperatures above 250 degrees C, which make it challenging to converse SC-PLA into useful products using versatile melt-processing technologies. With these challenges in mind, in this work, we propose a facile and practical strategy to fabricate SC-PLA products with exceptional thermo-mechanical properties through low-temperature melt-processing of SC-PLA powder with a bimodal melting temperature distribution. The results show that the melting temperature (T-m) bimodality makes SC-PLA powder able to be easily injection molded at a relatively low temperature of 210 degrees C (between the two T(m)s) due to the selective melting of the low-T-m SC-PLA component (SC-lPLA, ca. 20-40 wt%), indicating a good melt-proces-sability. Meanwhile, the high-T-m SC-PLA (SC-hPLA) component can directly deliver its desirable properties to the injection molded SC-PLA products. More importantly, during the injection molding process, the unmelted SC-hPLA particles can also induce the exclusive SC crystallization of the SC-lPLA melt as nucleating agent and greatly amplify the shear stress imposed on the melt as "rigid particles", finally generating numerous oriented SC structure in the SC-lPLA. Consequently, the injection molded SC-hPLA/SC-lPLA products exhibit impressively high tensile strength (74.3 MPa) and Vicat softening temperature (211.6 degrees C). Overall, this work presents an effective guidance for achieving desirable melt-processability of SC-PLA without sacrificing its thermo-mechanical properties and provides an industrial processing route towards high-performance SC-PLA products.
