    摘要: A polymer of ethylenically unsaturated monomer, for example, 1,3-butadiene, having a desired molecular weight and distribution thereof is produced, with a high stability, by preparing a solution of hydrogen in an inert organic solvent for the monomer in which a vapor-liquid phase equilibrium of hydrogen is attained, and then by addition-polymerizing the monomer in the hydrogen-dissolved inert organic solvent in the presence of a catalyst preferably including a metallocene complex of transition metal compound, an inert compound of a non-coordination anionic compound with a cationic compound, an organic metal (aluminum) compound and, optionally, water.

    摘要: 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.
