Abstract
Aluminum trihydrocarbyls are prepared by reacting an organo magnesium compound with a mixture of chlorinated and brominated aluminum compounds. There is thus obtained a mixture of aluminum trihydrocarbyls and a magnesium halide containing both chloride and bromine. The aluminum trihydrocarbyls are then recovered from the mixture. They may be used in the preparation of an alpha olfin polymerization catalyst as hereinafter described.
