The Zigler-Natta catalyst composition of the present disclosure provides uniform polyethylene having a molecular weight in the range from 1 million g/mol to 12 million g/mol. The Zigler-Natta catalyst composition of the present disclosure comprises external electron donor selected from the group consisting of substituted silanediyl diacetate, trialkyl borate and tetraalkoxysilane.

Ziegler-Natta catalyst composition for preparing polyethylene

The present disclosure relates to a single-pot multi step process for the preparation of a shape controlled pro-catalyst. The process comprises the steps of: i. reacting magnesium metal and at least one alkanol to obtain spheroidal magnesium alkoxide; ii. treating the spheroidal magnesium alkoxide with at least one transition metal tetrahalide, at least one organic modifier, and optionally, at least one in-organic modifier in the presence of at least one solvent to obtain a reaction mixture; iii. cooling, settling the reaction mixture and decanting the supernatant; iv. adding at least one transition metal tetrahalide, at least one solvent and optionally, at least one organic or inorganic modifier; and v. iterating steps (iii) and (iv) to obtain the shape controlled pro-catalyst.

The present disclosure relates to a single-pot process for the preparation of a shape controlled pro-catalyst. The process comprises the steps of i. reacting at least one alkanol with magnesium metal using at least one modifier and optionally, at least one solvent resulting in evolution of hydrogen gas, increasing the evolution of the hydrogen gas in a controlled manner by increasing the temperature in a graded manner to 100&#xb0; C. to obtain a mass, and ii. subjecting the mass to drying to obtain a free flowing procatalyst.
