Abstract

A drag-reducing suspension is described, along with a process for manufacturing the drag-reducing suspension. The drag-reducing suspension is easily transprotable, non-hazardous, easily handled, and provides a significant increase in drag-reducing capability over existing products. The drag-reducing suspension is manufactured by grinding an ultra-high molecular weight, non-tacky polymer in the absence of a partitioning agent.
