Summary Alkyl aluminum halides are well established initiators for cationic polymerizations. They enable homogeneous polymerization processes in nonchlorinated hydrocarbon processes. Activity and polymer properties can be significantly affected by th

Summary: Catalyst systems for polymerization often exhibit variable and poorly controllable activity because of strong influences of trace components and catalyst preparation conditions. In cationic polymerizations in particular, determining catalyti

A simulation tool was developed for the industrial solution polymerization of 1,3-butadiene with a Nd-based homogeneous Ziegler-Natta catalyst system. Insight into underlying reaction mechanisms was gained from laboratory experiments. Besides the cha

We elucidate the presence of correlated back-and forth-jumps of polymer segments close to the glass transition. An analytically tractable model is introduced which allows to quantify the back-jump probability and hence the orientational memory. The r
