Propylene Polymerization over Titanium-Magnesium Catalyst: Effect of Hydrogen on the Content of Active Centers with Different Stereospecificity and Their Reactivity in Propagation Reaction

[Display omitted] •The number of active centers (CPi) with different stereospecificity was found.•Propagation rate constants for such centers (kPi) were calculated.•Effect of hydrogen on the CPi and kPi values was studied.•Portion of “dormant” centers was estimated. This paper presents data on the n...
