摘要： This invention relates to supported metallocene catalyst compositions useful for addition reactions of prochiral .alpha.-olefins. Polymers, specifically propylene polymers, produced with this catalyst possess higher stereoregularities and consequently higher melting points compared to propylene polymers produced using previously known supported metallocene catalysts.

The catalyst compositions comprise transition metal (i.e., metallocene) cations and beam comprising anionic activators in prescribed ratios on metal or metalloid oxide supports.
