发明名称 Olefin polymerization catalyst precursor
摘要 <p>High activity, stereoregular olefin polymerization catalysts are produced from an organoaluminum cocatalyst, a selectivity control agent and a procatalyst obtainable from a magnesium-containing, titanium-containing procatalyst precursor also containing at least one of alkoxide, optionally substituted phenoxide or trialkylborate moieties. The catalysts are useful in the polymerization or copolymerization of lower α-olefins, particularly propylene.</p>
