摘要：

A detailed study of reactively toughened poly(L-lactic acid) (PLLA)/glycidyl methacrylate grafted poly(ethylene octane) blends is reported, and stereocomplex (SC) formed from PDLA incorporated was used to adjust the phase morphology. It was found that blends with 20wt% of POE-GMA exhibited highest impact strength and incorporation of PDLA with 1wt% had further improved the impact toughness and tensile strength. SEM revealed that SC had induced the crushing of the dispersed phase-size of the blends. The simultaneous enhancement of impact and tensile strength induced by SC would provide a new strategy to accelerate the commercial use of toughened PLLA blends.
