The most important challenge in polymer/clay nanocamposites is the state of clay dispersion, while in blend/clay nanocamposites another challenge by means that location ofclay, in matrix phase, dispersed phase and/or at the interface, is involved. The main objective of the present work was tostudy the state of clay dispersion and its location in PP/PS blends together with the effect of different modifiers on its partitioning [1].
