titleOfInvention |
Cyclobutyl silanes for catalysts useful for making highly isotactic olefin polymers |
abstract |
One aspect of the present invention relates to a catalyst system for use in olefinic polymerization, containing a solid titanium catalyst component prepared by contacting a titanium compound and a magnesium compound; an organoaluminum compound having at least one aluminum-carbon bond; and an organosilicon compound comprising at least one of cyclobutyl group. Another aspect of the present invention relates to a method of making a catalyst for use in olefinic polymerization, involving the steps of reacting a Grignard reagent having a cyclobutyl group with an orthosilicate to provide an organosilicon compound having a cyclobutyl moiety; and combining the organosilicon compound with an organoaluminum compound having at least one aluminum-carbon bond and a solid titanium catalyst component prepared by contacting a titanium compound and a magnesium compound. |
