RISSynthesis and Microstructurral Study of Stereoblock Elastomeric Polypropylenes from Metallocene Catalyst (2-PhInd)2ZrCl2 Activated with Cocatalyst Mixtures
Year: 2013
Abstract:
Various elastomeric polypropylenes (PPs) are synthe-
sized through homogeneous propylene polymerization with met-
allocene catalyst (2-PhInd)2ZrCl2 in the presence of different
cocatalyst mixtures: ...
Similarities and Differences of the Active Sites in Basic and Advanced MgCl2-Supported Ziegler-Natta Propylene Polymerization Catalysts
Year: 2010
Abstract:
Though preparation procedures of heterogeneous Ziegler-Natta catalysts for propylene polymerization are sophisticated, it is uncertain whether the nature of the active sites is similar or different for different preparation ...
