In heterogeneous Ziegler-Natta catalysts for olefin polymerization, isolation of a single type of active sites is a kind of ambition, which would solve long-standing questions on the relationship between active site and polymer structures. In this pa

We have kinetically elucidated the origins of activity enhancement because of the addition of comonomer in Ziegler- Natta propylene polymerization, using stopped-flow and continu- ously purged polymerization. Stopped-flow polymerization (with the pol

Growing evidence indicates that the innate immune system and oxidative stress caused by gut-derived endotoxins play a key role in alcoholic liver disease (ALD). Intracellular mechanisms associated with endotoxin-induced signaling play a crucial role

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

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,
