ABSTRACT:
A di(polycyclic amino)dialkoxysilane which is of value as an auxiliary catalyst component for polymerizing an .alpha.-olefin to produce an .alpha.-olefin polymer having a high stereoregularity and a broad molecular weight distribution is prepared by reacting a secondary polycyclic-amine compound with an organomagnesium compound in an ether solvent, to produce a polycyclic-amido magnesium compound, and reacting the polycyclic-amido magnesium compound with a tetraalkoxysilane in a solvent mixture of an ether solvent and an inert hydrocarbon solvent.
