Effect of nanoclay of morphology of PBT/PP polymer blend

The effect of polar nanoclays (Cloisite 30B) on morphology of PBT/PP (80/20 %wt) polymer blends was investigated. The concentration of nanoclays was varied from 1, 3 and 5 phr of polymer blend. The SEM micrographs showed that polar nanoclays have great effect on dispersion and distribution of PP particles in PBT matrix. The rheological analysis indicated the viscosity of matrix phase (PBT) increased with the content of organpclays. With growing of matrix viscosity the capillary number increases and helps to break up of dispersed-phase (PP) particles
