    Abstract: Crude oils and residual fuel oils having improved pour point and flow properties are obtained by incorporating therein a small amount of a new terpolymer prepared from ethylene, a vinyl ester, and a dialkylvinyl carbinol. The terpolymer has a number average molecular weight of about 500-10,000 and suitably contains 45-80 wt. % ethylene, 10-25 wt. % vinyl ester of a fatty acid having up to about eight carbon atoms and 10-30 wt. % dialkylvinyl carbinol wherein the alkyl groups have up to about six carbon atoms.

    Abstract: A low pour point gas turbine fuel is prepared from a waxy crude by blending a 650*-750*F distillate fraction from a crude oil with a minor amount of a 350*-650*F fraction of a middle distillate and from 0.05 to 0.5% by weight of an oil soluble ethylene-vinyl fatty acid ester copolymer in which the fatty acid component of the ester has a carbon content of from about 2 to about 6; the copolymer having a molecular weight between about 17,000 and 29,000, and a vinyl fatty acid ester content of from about 27 to about 42. The melt index of the copolymer ranges from 7 to 465.

    Abstract: An improved process for the transportation of waxy crude oils through pipelines, in particular North African crudes, which comprises introducing into the pipeline a low-pour point, lowsulfur crude oil blend comprising about 70 to about 90 percent by volume of a high-pour point, low-sulfur, waxy crude, and about 30 to about 10 percent by volume of a low-wax, low-pour crude, together with an effective pour depressant amount of an oilsoluble ethylene-vinyl fatty acid ester copolymer. The pipeline flow characteristics of the blend of the crudes are distinctly superior to the high-pour point, low-sulfur, waxy crude forming the major portion of the blend or the high-pour point, waxy crude with the same pour point depressant. In another aspect, this invention relates to the composition comprising the blended crudes together with the oil-soluble copolymer and to a process for preparing such compositions.
