Production of polymeric membranes made of polypropylene, poly(ethylene-co-vinyl acetate), and poly(vinyl alcohol)
In this study, we prepared and characterized membranes containing polypropylene, poly(ethylene-co-vinyl acetate) (EVA), and poly(vinyl alcohol) (PVA). The production process involved blend extrusion and calendering followed by solvent extraction by toluene and water of the EVA and PVA phases. Morpho...

| Sumario: | In this study, we prepared and characterized membranes containing polypropylene, poly(ethylene-co-vinyl acetate) (EVA), and poly(vinyl alcohol) (PVA). The production process involved blend extrusion and calendering followed by solvent extraction by toluene and water of the EVA and PVA phases. Morphology studies involving scanning electron microscopy determined the pore size distribution at the surface and in the internal regions of the membrane. The resulting membrane properties were related to the processing variables (extension rate, process temperature, and solvent extraction methods) and blend composition. |
