CATALYST COMPOSITION FOR COPOLYMERIZING ETHYLENE |
摘要 |
<p>Ethylene copolymers having improved resistance to pinstriping and gel streaking when extruded into film can be produced by continuously copolymerizing ethylene with one or more higher alpha olefin monomers in a low pressure gas phase reaction with a catalyst composition prepared by forming a precursor composition from a magnesium compound, titanium compound, and electron donor compound; diluting said precursor composition with a silica support which has been treated with a dialkylzinc compound; and activating the diluted precursor composition with an organoaluminum compound.</p> |
