50 years ago, Karl Ziegler and Giulio Natta were awarded the Nobel Prize for their discovery
of the catalytic polymerization of ethylene and propylene using titanium compounds and …

Abstract The innovation of Ziegler-Natta (ZN) catalysts opened a novel aspect of chemistry in
terms of polyolefin formation. Significant progress of more than fifty years in catalytic olefin …

Four R1R2Si (OMe) 2 type compounds were added as an external electron donor (De) in
propylene polymerization with TiCl4/Di/MgCl2 type supported Ziegler–Natta catalysts (Di …

Insight into the impact of mixed internal donors, comprising bis-methoxymethyl-fluorene
(BMF) and 2, 2-diisopropyl succinate (DIS), on the crystalline structure of MgCl2 supported …

Hexene polymerizations catalyzed by three kinds of MgCl 2-supported Ziegler–Natta
catalysts respectively, in which Cat-1 contains no internal donor (ID), Cat-2 contains …

ABSTRACT Two TiCl4/Di/MgCl2 type supported Ziegler–Natta catalysts were prepared by
loading dibutylphthalate or dicyclopentyldimethoxysilane (DCPDMS)(internal donor, Di) and …

In this study different water containing adducts, with MgCl 2· nEtOH· mH 2 O formula, were
synthesized through melt quenching method. After characterization of support samples, the …

The role of malonate compounds as electron donors in the propylene polymerization using
Ziegler–Natta (ZN) catalyst were investigated. Adsorption modes of a malonate compound …

Magnesium dichloride supported titanium catalyst incorporated with varying concentration of
ethylbenzoate and diisobutyl phthalate together as internal donor are synthesized. The …
