1Rheological behavior of PBT/PP/Organoclay nanocomposites

In this research the rheological behavior of Poly (buthylene terephthalate)/Polypropylene (80/20 %wt) reinforced with two types of Organoclays (Cloisite 15A and Cloisite 30B) was investigated by parallel plate rheometer and X-ray diffractometer (XRD). XRD patterns of nanocomposites revealed that interlayer spacing in nanocomposites reinforced with Cloisite 30B (hydrophilic nanoclay) was totally more than nanocomposites based on Cloisite 15A (hydrophobic nanoclay). The results of complex viscosity and storage modulus indicated that Cloisite 30B has more powerful effect Transition the rheological behavior from liquid-like to solid-like in PBT/PP/Organoclay nanocomposites, in particular with using of Cloisite 30B, was found to be consistent with formation of three dimensional physical networks
