In situ light and TEM microscopy observations of polypropylene formation over a TiCl4-MgCl2 supported Ziegler-Natta catalyst have been performed by video recording in real time. Polymer formation was confirmed by TG-DTA. The morphologies of the catalyst and polymer particles were characterized by the combination of ex situ light microscopy, SEM/EDX, conventional and high-resolution TEM, and STEM/PEELS/EDX.
