Abstract
Aluminum-containing compositions for use particularly as olefin polymerization or copolymerization cocatalysts are produced by reaction of trialkylaluminums or dialkylaluminum hydrides with 1,3- or 1,4-pentadiene at a mole ratio of aluminum compound to pentadiene of approximately 1:1, with removal during the reaction of evolved olefin.
