摘要: Nanocomposites containing polypropylene (PP), PET, and montmorillonite were prepared in a twin-screw extruder. X-ray diffraction, transmission electron microscopy, scanning atomic force polarized optical differential calorimetry used to characterize the samples. Intercalated exfoliated morphology observed nanocomposites. The PET domains usually presented spherical shapes they start point PP crystallization. average diameter number of was evaluated. influence addition PP-MA as compatibilizer on PP/PET investigated. interconnected nanocomposite PP-MA. clay located predominantly interphase phase. crystallization process monitored rate slower © 2008 Wiley Periodicals, Inc.
