Therefore, in this work, the new commercially available ultrafine fully vulcanized powdered ethyl acrylate rubber (EA-UFPR) was used as the toughening modifier for PLA.
High-performance PLA blends with excellent tensile toughness was indeed successfully achieved without sacrificing its stiffness.
The mechanism for the high efficiency
toughening effect of UFPR on PLA is discussed based on the morphology of UFPR, its dispersion in PLA matrix and the interfacial interaction.
