titleOfInvention |
Shape-shifted magnesium alkoxide component for polymerizing olefins |
abstract |
A process is provided for preparing a shape-shifted catalyst component comprising (1) contacting a dihydrocarbyloxide magnesium compound with carbon dioxide in the presence of a slurrying agent to form a slurry of a carboxylated dihydrocarbyloxide magnesium compound; (2) adding a filler to the slurry either before or after the carboxylation of step (1); (3) spray drying the slurry of step (2) to evaporate the slurrying agent and to produce solid particles of the carboxylated dihydrocarbyloxide magnesium compound incorporating the filler; and, optionally, (4) heating the solid particles to remove carbon dioxide to produce a shape-shifted dihydrocarbyloxide magnesium compound component. A catalyst system using the component and a polymerization process employing the catalyst system are also provided. |
