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 decilitcrs per gram, the process comprising:contacting alpha olelin monomers with a catalyst system in a reactant mixture,wherein the catalyst system includes a transition metal catalyst, an alkylaluminoxane co-catalyst, and a halohydrocarbon; andpolymerizing the alpha olelin 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.
