## Abstract Summary: Stopped‐flow polymerization of propene was first conducted at 40 °C using the TiCl~4~/DBP/MgCl~2~ catalyst (DBP = dibutyl phthalate) combined with Al(C~2~H~5~)~3~. An induction period was observed at the beginning of polymerization, and the resulted polymer contained a consider
