<p>Many liquids have properties improved, and fluid flow friction losses are reduced in flowing fluids by adding thereto a small, effective amount of composition comprising (i) a continuous phase of a liquid which is normally miscible with said fluid, and, dispersed therein, (ii) a stable discontinuous phase predominantly comprising fine particles of a high molecular weight polymer which is ultimately miscible with said fluid. In preferred features the compositions include a surface active agent. In other preferred features, friction is reduced in flowing hydrocarbons.</p> |
