Highly Active Half-Metallocene Chromium(lII) Catalysts for Ethylene Polymerization Activated by Trialkylaluminum.

The article presents a research about the development of a highly active half-metallocene chromium(III) catalyst system for ethylene polymerization. The new catalyst system, which is activated by trialkylaluminum, represents a remarkable addition to the limited list of half-metallocene type chromium ethylene polymerization catalysts.
