Unprecedented coordination–insertion polymerizations of polar methoxyl substituted styrene derivatives, in despite of the position of the substituent, have been achieved using a pyridyl methylene fluorenyl yttrium bis(alkyl) precursor with high activity to give polar polystyrenes of high molecular weight and perfect syndiotacticity.
