Preparation of MgCl2-Supported Ziegler-Natta Catalysts via New Surfactants Emulsion for Propylene Polymerization

Yansong Wu et al.

Summary: The MgCl2-supported Ziegler-Natta catalyst for propylene polymerization prepared via an in situ emulsion technique with new surfactants shows perfectly spherical particles, narrow size distribution, and low fine powder content. The catalyst demonstrates high activity, high bulk density, high stereospecificity, and excellent hydrogen sensitivity during propylene bulk polymerization. The produced polymer has a narrow particle size distribution and low fine powder content.

Synthesis of novel Ziegler Natta catalyst in the presence of internal promoter and electron donors for ethylene and ethylene/1-hexene polymerization

Hossein Bazgir et al.

Summary: This study investigated the simultaneous effect of cyclohexyl chloride (CHC) and various electron donors (ED) on ethylene polymerization, elucidating their significant impact on catalyst activity and polymer product properties. The use of methanol and diethyl ether (DEE) as EDs led to increased catalyst activity and improved characteristics of the produced polyethylene. The morphology of the catalysts was positively affected by the presence of CHC and ED, with differences observed in the influence of methanol and DEE on catalyst porosity and fragmentation phenomena.
