Abstract
A drag-reducing polymer is described, along with a method for manufacturing the drag-reducing polymer. The drag-reducing polymer is manufactured by bulk polymerizing a vinyl aromatic with an &agr;-olefin, wherein the &agr;-olefin has a carbon chain length of between two and twenty carbons. A drag-reducing polymer suspension and drag-reducing polymer solution are also described.
