    摘要： A catalyst system for the (co)polymerization of propylene contains (A) a solid catalyst component comprising titanium, magnesium, halogen and a 1,3-diether; (B) an organic aluminum compound; and optionally (C) an organic silicon compound. In comparison with the prior art, stereospecificity of the polymer prepared by using the catalyst system of this invention evenl containing no external electron-donor is greater than 99%. Also, the activity of the catalyst system and hydrogen gas adjustability on the molecular weight of the polymer do not significantly decrease.
