Abstract:
The method of improving the low temperature CFPP flow properties of an oil having a wax content of at least 2.5% by weight, measured at 10.degree. C. below cloud point, comprising adding to the oil an oil soluble ethylene-vinyl ester copolymer having, in addition to units derived from ethylene, vinyl acetate units and units of the formula --CH.sub.2 CROOCR.sup.1, wherein R represents H or CH.sub.3 and R.sup.1 represents a hydrocarbyl group having at least 2 carbon atoms, the copolymer having from 1 to 6 methyl groups per 100 methylene units, the improvement in low temperature CFPP flow properties being relative to an identical oil having added thereto ethylene-vinyl acetate copolymers.
