Polymer slurries of ultrahigh molecular weight polyalpha-olefins are made stable toward settling, separation and agglomeration by surface treatment with a combination of wax and optional relatively high-density particulates. The selection of the surface coating acts not only as an anti-blocking agent, or partitioning aid to keep the tacky polymer particles separated, but also provides the suspended polymer particle with a density that matches the carrier. This prevents separation of the slurry components over time. Such materials, ultimately used as pipeline additives to reduce the fluid drag and increase the volumetric throughput, can be stored and shipped for extended periods of time without degradation of the slurry quality. Upon injection into the pipeline, the polymer particle dissolves quickly, unhindered by the coating.
