## Abstract Inversion of stereoselectivity of a particular metallocene (Me~2~Si(Flu) (N‐__t__‐Bu)ZrCl~2~) (Me: methyl, Flu: fluorenyl, __t__‐Bu: __tert__‐butyl) from syndiospecific into isospecific was observed by changing the cocatalyst from methylaluminoxane (MAO) to [Ph~3~C]^+^ [B(C~6~F~5~)~4~]^

Methyl methacrylate was polymerized with Cp 2 YCl(THF) or IVB group metallocene compounds (i.e., Cp 2 ZrCl 2 and Cp 2 HfCl 2 , etc.), in the presence of a Lewis acid like Zn(C 2 H 5 ) 2 . The Lewis acid was complexed with methyl methacrylate, which avoided the metallocene compounds being poisoned wi
