Ziegler-Natta Catalyst Composition And A Process For Its Preparation

摘要

The present disclosure relates to a Ziegler-Natta catalyst composition comprising: i. at least one pro-catalyst comprising: a morphologically modified magnesium alkoxide as a support; at least one titanium halide; at least one first internal donor and at least one second internal donor; and at least one inert hydrocarbon medium, ii. at least one organo-aluminum compound as a co-catalyst; and iii. at least one external donor comprising an organo-silane compound and a carboxylic acid ester. The present disclosure also relates to a process for the preparation of the Ziegler-Natta catalyst composition.
