Mixing polymers has attracted a lot of attention in the recent decades because of both technical and economical advantages. It is possible to achieve new and unique properties by mixingtwo or more polymers; however, properties of a blend are related to its final morphological structure, which is affectedby variation of volume fraction of constituents and process parameters. It is essential to acquire a mechanical model which signifies the whole morphological structure of theblend, which is strongly affected by variation of volume fractions of dispersed phase[1].
