Abstract
A unique high efficiency catalyst has been developed for the polymerization of ethylene. The activity of the catalyst, which uses a mixed magnesium-aluminum alkyl as a reducing agent for tetrabutyltitanate, and hydrogen chloride to deactivate excess reducing agent, is dependent on a specific and unpredicted order of addition of catalyst components.
