The outstandingly rapid scientific and technological development of metallocene-based
catalysts for olefin polymerization is a perfect example of the successful application of …

Abstract Since 1963, when Karl Ziegler and Giulio Natta were jointly awarded the Nobel
Prize for their discoveries of the catalytic polymerization of olefins with Ti-chlorides and Al …

We present a theoretical study of the basic interactions occurring at supported
hetereogenous Ziegler− Natta catalytic systems. We first investigated the interaction …

Isotactic polypropylene (iPP) is a thermoplastic material of vast importance. The ever-
increasing demand for it is derived from its useful physical properties and the availability of …

Poly (propylene) s prepared using MgCl2‐supported catalysts containing different electron
donors have been characterized using temperature rising elution fractionation (TREF), gel …

The fundamental factors determining the performance of state‐of‐the‐art MgCl2‐supported
catalysts for polypropylene are becoming increasingly evident. Polymer yield, isotacticity …

A comparative analysis of the polymorphic behavior of samples of isotactic polypropylene
(iPP) prepared with heterogeneous Ziegler− Natta catalysts and with a single-center …

Selective catalysts can be considered as nanomachines designed to perform the synthesis
of molecules with high reaction activity and high selectivity. These properties arise from a …

The microstructures of two poly (propylene) s with matched molar masses and overall defect
concentrations are inferred from the crystallization behavior of their narrow molar mass …

TiCl4/MgCl2 catalysts are still the main industrial catalyst for isotactic polypropylene at
present. However, the mechanism of isotactic polymerization of propylene has not been fully …
