This work focuses on the study of uniaxial elongational flow and to its effect on morphology of polymer-layered silicate nanocomposites. In particular hybrids at different silicate loadings were produced by melt compounding using two polyamide matrices: a polyamide-6 and a commercial copolyamide, having similar molecular weights. The elongational flow characterization was realized by converging flow method and fiber spinning technique by making use of a capillary rheometer. The structural changes of the layered silicate and crystalline regions of the fibers were investigated, in response to uniaxial deformation imposed, through analytical techniques sensitive to different aspects of the hybrids morphology, such as DSC, X-Ray diffraction and TEM analysis.
