Morfological properties of isotatic polypropylene, i-PP, submitted to a planar-strain compression

Year: 2001

Type: conference-paper

Abstract: The morphological properties of the isotatic polypropylene (i-PP) submitted to plane deformation were investigated through x-ray diffraction and transmission electron microscopy.Two crystalline phase were identified in the undeformed polymer, namely α and β phase, although some amorphous hallo coexist with these phases.After deformation with 10 MPa, a transition from the β to α phase occurs together with an increase of the amorphous contribution.The relaxation of internal energy during the uniaxial deformation can generate a high temperature pulse, which can be responsible by the phase transition as well as the decrease of crystallinity.
