摘要：
In situ gas phase polypropylene (PP) formation over heterogeneous ballmilled TiCl4-MgCl2 Ziegler-Natta (Z-N) catalysts has been observed for the first time in real time using environmental TEM (ETEM). The active Ti sites appear to be located at the polymer/MgCl2 buried interface. Our data show that the polymerization probability is about 10(-5)-10(-4).
