Abstract

The activity of Ziegler-Natta catalysts for olefin polymerization has been remarkably increased by supporting the titanium compound on a solid carrier.1–23 A variety of metal halides have been reported as carriers, the most common being magnesium chloride (MgCl2) which was originally observed by Petrochemicals Ltd.24 and She11.25 The marked improvement of the activity by using MgCl2 has been revealed to be attributed to a significant increase in the propagation rate as well as a considerable increase in the number of active species.16–20 However, the precise reason why MgCl2 accelerates the propagation rate is quite open to discussion.
