The present invention relates to a process for preparing ultra-high molecular weight polyalphaolefin. The process consists of polymerizing alphaolefin monomers using the catalyst system consisting of supported Ziegler-Natta catalyst without internal donor in presence of co-catalyst based on alkyl aluminums. The resulting ultra-high molecular weight polyalphaolefins having intrinsic viscosity &#x2265;10 dL/g are used as drag reducing polymers for increasing throughput in the pipelines by reducing frictional resistance in turbulent flow.

Process of preparation of drag reducing polymers and usage thereof

The present invention describes a process for preparation of catalyst component comprising contacting magnesium based precursor along with an internal donor based on phenylene dioates with an acyl halides in a solvent to obtain a solid precatalyst component; and contacting the solid precatalyst component with transition metal compound to obtain the catalyst component. The present invention also relates to a process for preparation of a catalyst system from said catalyst component and preparation of a polyolefins having free flowing characteristics with bulk densities (BD) of at least about 0.3 g/cc from the catalyst system.

Catalyst process modification and polymerization thereof

The present invention describes a process for preparing catalyst for the polymerization of ethylene consisting essentially of the steps of (i) contacting a magnesium based precursor with a solvent; and (ii) then contacting the magnesium based precursor in the solvent with a transition metal compound to obtain the catalyst, wherein step (ii) is single contact step. The present invention also relates to a process for preparation of a catalyst system and a process of polymerizing and/or copolymerizing of ethylene to obtain a polyethylene using the catalyst.
