  Improved Ziegler-Natta catalysts and methods of making the improved catalyst are described. The Ziegler-Natta catalyst is formed using a spherical MgCh-xROH support, where R is a linear, cyclic or branched hydrocarbon unit with 1-10 carbon atoms and where ROH is an alcohol or a mixture of at least two different alcohols and where x has a range of 1.5 to 6.0, preferably 2.5 to 4, more preferably 2.9 to 3.4, and even more preferably 2.95 to 3.35. The Ziegler-Natta catalyst includes a Group 4-8 transition metal and an internal donor comprising a phthalate-free diether compound. The catalyst has improved activity in olefin polymerization reactions as well as good stereoregularity and hydrogen sensitivity, and may be useful in the production of phthalate-free propylene polymers having a molecular weight distribution (PI(GPC)) in the range from about 5.75 to about 9.

  本文描述了改进型 Ziegler-Natta 催化剂和制造改进型催化剂的方法。Ziegler-Natta 催化剂是使用球形 MgCh-xROH 载体形成的，其中 R 是具有 1-10 个碳原子的线性、环状或支链烃单元，ROH 是醇或至少两种不同醇的混合物，x 的范围是 1.5 至 6.0，优选 2.5 至 4，更优选 2.9 至 3.4，更优选 2.95 至 3.35。Ziegler-Natta 催化剂包括 4-8 族过渡金属和由不含邻苯二甲酸酯的二醚化合物组成的内部供体。该催化剂在烯烃聚合反应中具有更高的活性以及良好的立体规整性和氢敏感性，可用于生产分子量分布（PI(GPC)）在约 5.75 至约 9 范围内的不含邻苯二甲酸酯的丙烯聚合物。
