Abstract

A composition including a polyalphaolefin and at least one alfol alcohol that function as drag reducing agent slurries and a process for the preparation of the drag reducing agent slurries are disclosed. The process includes contacting alpha olefin monomers with a catalyst in a reactant mixture to form a polyalphaolefin. The polyalphaolefin is combined with at least one alfol alcohol to form a drag reducing agent slurry. A process for reducing drag in a conduit is also disclosed.
