  A solid titanium catalyst component (I) of the present invention is characterized in that it contains titanium, magnesium, halogen, and a cyclic ester compound (a) represented by the following formula (1) : wherein n is an integer of 5 to 10; R2 and R3 are each independently COOR1 or R, and at least one of R2 and R3 is COOR1; a single bond (excluding Ca-Ca bonds, and a Ca-Cb bond in the case where R3 is R) in the cyclic backbone may be replaced with a double bond; a plurality of R1's are each independently a monovalent hydrocarbon group having 1 to 20 carbon atoms; and a plurality of R' s are each independently a hydrogen atom or a substituent, but at least one of R's is not a hydrogen atom. When using this solid titanium catalyst component (I), an olefin polymer having a broad molecular weight distribution can be produced.

  本发明的固体钛催化剂组分（I）的特征在于它含有钛、镁、卤素和由下式（1）表示的环酯化合物（a）： 其中 n 为 5 至 10 的整数； R2 和 R3 各自独立地为 COOR1 或 R，且 R2 和 R3 中至少有一个为 COOR1； 环状骨架中的单键（不包括 Ca-Ca 键，在 R3 为 R 的情况下为 Ca-Cb 键）可被双键取代； 多个 R1 分别独立地为具有 1 至 20 个碳原子的单价烃基；以及 多个 R'各自独立地为氢原子或取代基，但至少有一个 R'不是氢原子。使用这种固体钛催化剂组分 (I)，可以生产出具有宽分子量分布的烯烃聚合物。
