<p>A drag reducing composition containing 25 to 70% by weight of a finely divided solid polyolefin friction reducing agent formed from mono olefins containing from to 2 to 30 carbon atoms and 30 to 65% by weight of a fatty acid suspending medium which is a stable liquid in the temperature range of from 10 to 100°C, the composition being formed by finely dividing the solid polyolefin reducing agent to produce a free flowing particulate polyolefin material and suspending the particulate polyolefin material in the suspending medium.</p> |
