Olefin polymerization, catalyst, and precursor therefor |
| abstract |
A generally dipyramidal-shaped catalyst precursor is prepared by dissolving magnesium dichloride and a suitable alcohol in a suitable solvent and then cooling to obtain a precipitate of the desired shape. The use of the precursor to prepare catalysts and the use of the catalysts to prepare polymers is also disclosed. |
