Different nanocomposites based on isotactic polypropylene (iPP) and mesoporous SBA-15 silica have been prepared by melt extrusion as an attempt of incorporating iPP within the nanometric SBA-15 pores by the action of shear forces during processing. T

Nanocomposites based on isotactic polypropylene (iPP) and mesoporous silica particles of either MCM-41 or SBA-15 were prepared by melt extrusion. The effect of the silica incorporated into an iPP matrix was firstly detected in the degradation behavio
