Polyolefin catalyst from metal alkoxides or dialkyls, production and use |
摘要 |
<p>A method of forming a polyolefin catalyst component which includes chlorinating magnesium ethoxide, solubilizing the chlorinated magnesium ethoxide into a hydrocarbon solvent utilizing an alcohol, and then precipitating a solid from the solvent by the dropwise addition of titanium tetrachloride. Two more titanation steps follow, the first with an electron donor, the second without an electron donor, to produce a catalyst having an improved yield.</p> |
