    Abstract: Block polymers of organosiloxane and polyalkylene oxide are used in middle distillate petroleum fuel oils for separating out or otherwise reducing water haze in the oil. These block polymers are particularly useful in heating oils and diesel fuels, containing wax crystal modifier additives to improve the low temperature flow properties of the oil, particularly those modifiers which are copolymers of ethylene and an unsaturated ester and which have a tendency to stabilize and maintain the water haze in the oil.

    Abstract: Many liquids have properties improved, and fluid flow friction losses are reduced in flowing fluids by adding thereby 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.

    Abstract: A process for reducing oxidative degradation and cold flow of polymer crumb by immersing the crumb in a non-solvent such as water and/or dusting the crumb with a powder such as calcium carbonate and 2,6 di-t-butylparacresol, 4,4''-methylene-bis-(2,6 di-t-butylphenol) or other antioxidants. A process for reducing fluid flow friction loss in pipeline transmission of a hydrocarbon fluid by providing a continuous source of dissolved polymer therein by injecting polymer crumb or a slurry of polymer crumb and water into the hydrocarbon fluid, whereby the crumb gradually and continuously dissolves during transmission of the crumb through the pipeline.
