PP/PET thermostimulative shape memory blends at composition 90/10, which used POE-g-MAH as a reactive compatibilizer, were prepared by melting extrusion. The results of SEM, POM, DSC, mechanical property, shape memory property, and melt rheological behavior showed that addition of POE-g-MAH improved compatibility between PP and PET, increased interaction between the two phases, and reduced size of the dispersive PET phase and crystallization ability of PP. Moderate POE-g-MAH could enhanced the shape memory property of the blends, meanwhile improved the mechanical properties and the processing performance. When concentration of POE-g-MAH was 5-7phr, the blends had a better comprehensive performance.
