    Abstract Poly(phenylene oxide)/renewable polyamide 11 (PPO/PA11 20/80) blends toughened with glycidyl methacrylate grafted ethylene-n-octene copolymer (GEOC) were prepared in a co-rotating twin-screw extruder. The reaction between GEOC and PPO/PA11 blend was analyzed by gel content tests. The morphology of PPO/PA11/GEOC blends was observed by scanning electron microscope. The SEM results showed that PPO formed the continuous phase, though it is a minority component of blends. With increasing GEOC content from 5 to 15 wt% the morphology of the blends transformed from droplet-matrix to co-continuous structure, in which both PA11 and PPO phases are continuous. The blend with co-continuous morphology had better… More >
