Methods for forming amorphous ultra-high molecular weight polyolefins for use as drag reducing agents

A process for forming a drag reducing agent comprising a substantially non-crystalline, ultra-high molecular weight polyolefin, the process comprising:

• isomerizing olefin monomers to form isomerized olefin monomers, wherein the isomerized olefin monomers are substantially free of branched olefin monomers;
• contacting isomerized olefin monomers with a catalyst system in a reactant mixture, wherein the catalyst system includes at least one catalyst and at least one co-catalyst;
• and
• polymerizing the isomerized olefin monomers at a temperature at about or less than 25° C., wherein during the polymerization, at least a portion of the isomerized olefin monomers polymerize in the reactant mixture to provide a substantially non-crystalline, ultra-high molecular weight polyolefin.
