Abstract
Propylene homopolymerizations were conducted by using three kinds of metallocenes: Cp2ZrCl2, En(Ind)2ZrCl2 and iPr(Cp)(Flu)ZrCl2, all of which were activated with methylaluminoxane. Detailed NMR analyses of the chain ends in the resulting polymers were carried out to discuss the chain end structures of the polypropylenes and the mechanism of polymerization. The characteristic of each metallocene for the mechanism of polymerization was also described.
