The deactivation behaviors of TiCl3/MgCl2 model catalysts with molecularly dispersed TiCl3 were investigated to clarify the role of the dispersion state of the Ti species in the deactivation of MgCl2-supported Ziegler-Natta (ZN) catalysts for propyle

The dispersion state of surface Ti species is one of the most important factors for polymerization properties of MgCl_2-supported heterogeneous Ziegler-Natta catalysts. In this paper, ethylene-propylene copolymerization was conducted using a novel Zi

Modeling study was carried out for JPP-HORIZONE, which has horizontally stirred gas reactors in which the heat of polymerization is removed by vaporization of liquid propylene (LPP). The effects of LPP were estimated by the model which has a couple o

Hydrogen effects for propylene polymerization were investigated with ultra low TiCl 3 loading MgCl 2 -supported catalysts in which the electric states of Ti species can be almost uniform. Hydrogen did not affect the catalyst activity, while the effic

The relationship between the stereospecificity of active sites and hydrogen effects on propylene polymerization was investigated for MgCl 2 -supported TiCl 3 catalysts at ultra-low Ti contents. Hydrogen had no effect on the catalyst activities for is

In propylene polymerization with MgCl(2) -supported Ziegler-Natta catalysts, it is known that the reduction of TiCl(4) with alkylaluminum generates Ti(3+) active species, and at the same time, leads to the growth of TiCl(x) aggregates. In this study,
