摘要：
A process for producing highly stereoregular .alpha.-olefin polymers which comprises polymerizing .alpha.-olefins in the presence of a catalyst system comprising:(A) a solid catalyst obtained by contact reaction between(a) a solid product prepared by reacting an organo-magnesium compound with at least one of halogenated silicon compound (I) and halogenated aluminum compound (II) in a solvent and(b) a titanium compound having both titanium-aryloxy and titanium-halogen linkages, and(B) an organo-aluminum compound as an activating agent.
