Abstract: The present disclosure relates to a process for preparation of a catalyst with a polyolefin coat. The process of the present disclosure is simple, economical and requires 50% less reaction time to obtain a desired catalyst with polyolefin coat. The catalyst obtained by the process of the present disclosure is capable of reducing generation of polymer fines by at least 50%, which leads to improved plant operability and throughput.

Abstract: The present disclosure relates to a polyolefin characterized by melt flow index ranging from 1 and 100 g/10 min; tacticity ranging from 97 and 99.5%; and porosity ranging from 0.1 to 0.4 cm3/g. The present disclosure also relates to a simple and economic method for preparing the polyolefin.

Abstract: The present disclosure relates to a process for controlling particle size distribution of a Ziegler-Natta catalyst composition. In order to control the particle size distribution, magnesium metal is reacted with a mixture comprising a first alcohol and a second alcohol to obtain a slurry which includes a mixture of magnesium alkoxides and unreacted alcohol. The unreacted alcohol is separated from the slurry to obtain the mixture of magnesium alkoxides having reduced methoxy content less than 2 wt %. The mixture of magnesium alkoxides is chlorinated to obtain a Ziegler-Natta pro-catalyst. The Ziegler-Natta pro-catalyst is mixed with a co-catalyst to obtain a Ziegler-Natta catalyst composition with controlled particle size distribution in the range of 5 ?m to 15 ?m.

Abstract: 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.
