METHOD OF MAKING ZIEGLER-NATTA TYPE CATALYSTS |
摘要 |
A process for making a Ziegler-Natta-type catalyst precursor including contacting a Group 4 metal compound with one or more Titanium compounds selected from the group of TiCl3 (Al-activated or hydrogen-reduced), and Ti(OR)4 where R is ethyl, isopropyl or butyl in the presence of an alcohol solution having at least one C2-C4 alcohol and at least one of MgCl2 and magnesium compounds which form MgCl2 in the presence of the alcohol solution to form a catalyst precursor solution is provided. Also provided are catalysts made from the precursors produced by the process. Also provided are polymers made using the catalysts.
