Effect of Mesoporous SBA-15 Silica on the Thermal Stability of isotactic Polypropylene based Nanocomposites prepared by Melt Extrusion

The influence of mesoporous SBA-15 on the thermal stability of nanocomposites with isotactic polypropylene has been evaluated in detail, both under inert and air conditions, by performing dynamic weight loss measurements and by tracking the evolution of degradation species in materials prepared by m...
