The present results obtained for PLA/EGMA blends are compared to those reported for other PLA blend systems. In one
study ternary blends composed of poly(L-lactide) (PLLA), LDPE, and PE-b-PLLA prepared by solution blending were studied [12]. The tensile and Izod impact testing results on the ternary blends showed a significant improvement in toughness as compared to the PLLA homopolymer or the corresponding PLLA/LDPE binary blends. For example, in an (80/20/10) PLLA/LDPE/PE-b-PLLA sample, which gave the best mechanical properties, the elongation at break and the Izod impact strength increased respectively by 9 times (35%) and by 15 times compared with those of the neat PLA.
