Abstract Stopped‐flow (SF) polymerization is a powerful tool to investigate the nature of the active site of heterogeneous Ziegler‐Natta catalysts, but poor polymer yields due to short polymerization times limit detailed structural analyses of the obtained polymer. A new large‐scale SF polymerization system is described in which an arbitrary volume of slurry can be transferred to obtain a polymer yield sufficient for a variety of analytic purposes. The developed LSF system is proven to be highly scalable and stable, leading to reproducible polymerization in an expanded time range from 0.03 s to a few seconds. The accurate polymerization below 0.1 s is promising for future studies to evaluate accurate kinetics as well as dormant processes in Ziegler‐Natta olefin polymerization.
