Summary

As a support of titanium catalyst, the [MgCI2(THF)2] complex has been used. Reaction of TiCl4 with this support gave a stable and active catalyst for olefin polymerization. The effect of the catalyst synthesis conditions on its activity in ethylene polymerization has been investigated. A mathematical analysis of these results confirmed the presence of two types of active centres —superactive centres and classical centres. Conditions promoting the formation of superactive catalytic centres established.
