     polypropylene(pp)/polystyrene(ps) (pp/ps = 80/20) blend with different types of fillers were prepared by using melt method. four different types of fillers, namely mesoporous mcm-41 (without template), nano-sio2, polymethylmethacrylate (pmma)/mcm-41 and pmma/sio2 were considered. for pmma/mcm-41 filler, the synthesis of the filler consisting of entrapped strand of pmma within the pores of mesoporous mcm-41 (without template) was described. the mechanical properties of the blend determined as the nano-fillers contents and the different types of blend were found to vary with the different interface between fillers and the matrix. sem revealed a good interaction between the matrix phases and pmma/mcm-41 or mcm-41 (without template). the decreased tg of ps implied that the good adhesion between pp and ps blend was obtained by adding pmma/mcm-41 nano-filler.
