An on-line electron spin resonance (ESR) technique was applied to investigate the oxidation states of the metallocene catalysts CpTiCl 3 , CpZrCl 3 , Cp 2 TiCl 2 , and Cp 2 ZrCl 2 . These metallocene catalysts were activated by modified methylaluminoxane (MMAO). It was found that the titanocene cata
