| titleOfInvention |
Olefin polymerization catalyst precursor |
| abstract |
High activity, stereoregular olefin polymerizationncatalysts are produced from an organoaluminum cocatalyst, anselectivity control agent and a procatalyst obtainable fromna magnesium-containing, titanium-containing procatalystnprecursor also containing at least one of alkoxide,noptionally substituted phenoxide or trialkylborate moieties.nThe catalysts are useful in the polymerization orncopolymerization of lower α-olefins, particularly propylene. |
