    Abstract: Water-insoluble polyoxyalkylene graft copolymers are effective anti-foam agents for reducing foaming in crude oil/gas separators. The copolymers are of formula: ##STR1## wherein R is an ethylene, propylene or butene group or a mixture thereof;R' is a hydrocarbyl group containing 1 to 8 carbon atoms;R" is a hydroxyl group, an alkoxy group or an alkyl group containing 1 to 8 carbon atoms;(a) is a number in the range 100 to 250;(b) is a number in the range 1 to 6;(c) is a number in the range 1 to 10; and(d) is a number in the range 10 to 100.They are particularly useful in breaking microgas dispersions and foams resulting from crude oils with a high gas to oil ratio.

    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.
