Solid catalyst components and catalysts which comprise (a) a magnesium compound, (b) titanium tetra chloride, and (c) a phthalic acid diester or its derivative represented by a particular formula, can afford polymers of olefins in very high yield. Particularly, propylene polymers can be obtained in very high yield while retaining high stereoregularity. Moreover, they have high responsiveness to hydrogen.
由(a)镁化合物、(b)四氯化钛和(c)邻苯二甲酸二酯或其衍生物组成的固体催化剂组分和催化剂,能以非常高的产率获得烯烃聚合物。尤其是丙烯聚合物,产量非常高,同时还能保持较高的立体规整性。此外,它们对氢的反应性也很高。
