Abstract:
A process for forming a drag reducing agent comprising a non-crystalline, ultra-high molecular weight polyalphaolefin having an inherent viscosity of at least about 10 deciliters per gram, the process comprising:contacting alpha olefin monomers with a catalyst system in a reactant mixture, wherein the catalyst system includes a transition metal catalyst and a halohydrocarbon; andpolymerizing the alpha olefin monomers at a temperature at about or less than 25.degree. C., wherein during the polymerization, at least a portion of the alpha olefin monomers polymerize in the reactant mixture to provide a non-crystalline, ultra-high molecular weight polyalphaolefin.
