Abstract
Wide angle X-ray diffraction has been used to investigate polymorphism in isotactic polypropylene (IPP) mouldings produced by conventional i njection moulding and by shear controlled orientation injection mouldi ng (SCORIM). Gamma Phase was found to form in highly oriented IPP prod uced by SCORIM, with a marked enhancement of the preferred orientation of the alpha phase and percentage crystallinity when compared with co nventionally moulded IPP.
