Process for the preparation of spherical catalyst particles |
| abstract |
The present invention describes a process for preparing spherical particles of a catalyst composition, the process comprising contacting an organomagnesium precursor with a transition metal compound in presence of an internal donor to obtain a reaction mixture. Thereafter heating the reaction mixture from a first pre-determined temperature to a second pre-determined temperature and then heating the reaction mixture from second pre-determined temperature to a third pre-determined temperature to obtain spherical particles of the catalyst composition. The present invention also relates to a process for preparing of a spherical catalyst system from said spherical catalyst composition and preparing a spherical polyolefins having free flowing characteristics with bulk densities (BD) of at least about 0.4 g/cc from the spherical catalyst system. |
