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.
