Facile approach for largely refining phase domains of PMMA/PS blends and improving their properties during extrusion

The immiscible poly(methyl methacrylate)/polystyrene (PMMA/PS) blends with three composition ratios (80/20, 70/30, and 60/40 w/w) are prepared using water-assisted mixing extrusion (WAME). The injected high-pressure water during extrusion facilitates to significantly refine the phase domains without...
