Abstract

In this study, ternary blends consisting of polylactide (PLA) and two functional block copolymers, ethylene-glycidyl methacrylate (E-GMA) and ethylene-butyl acrylate-maleic anhydride (EBA-MAH), were prepared through a melt blending process. The blends were characterized using Fourier transform infrared (FTIR) analysis, which revealed that the functional groups GMA and MAH reacted with the terminal hydroxyl and carboxyl groups of polylactide (PLA), resulting in reactive compatibilization of the copolymers with PLA. Rheological measurements demonstrated that crosslink reactions occurred between E-GMA and EBA-MAH in the ternary blend. The shape memory effect (SME) of the blends was evaluated using the torsion method. The objective of this work was to enhance the toughness of PLA through crosslinking with E-GMA and EBA-MAH and to assess the shape memory effect of the resulting blends. The results showed that the blends were toughened and exhibited a satisfactory shape memory effect.
