Perspectives and limitations of metallocenes in the polyolefin industry
A metallocene is a compound typically consisting of two cyclopentadienyl anions (C 5H 5, abbreviated Cp) bound to a metal center (M) in the oxidation state II, with the resulting general formula (C5H5)2M. Closely related to the metallocenes are the metallocene derivatives, e.g. titanocene dichloride, … Meer weergeven The first metallocene to be classified was ferrocene, and was discovered simultaneously in 1951 by Kealy and Pauson, and Miller et al.
