Abstract: Copolymers are described of at least 75% by weight of tert-butyl styrene, from 1% to 24% by weight of a copolymerizable second monomer and from 1% to 10% by weight of methacrylic acid, the copolymers having certain specified solubility and rheological characteristics in AVTUR 50 aviation kerosene. A process for making the copolymers by aqueous emulsion polymerization of the monomers under certain defined conditions is also described. The copolymers are useful as additives to liquid hydrocarbon aircraft fuels for the purpose of reducing the tendency of such fuels to form inflammable mists under shock conditions.

Abstract: A crude oil composition having a low pour point is prepared by incorporating into a waxy crude oil an effective pour depressant amount of an oil-soluble polymer, such as vinyl acetate-ethylene-propylene or butylene terpolymer or a graft copolymer in which propylene or butylene is grafted onto an ethylene-vinyl acetate copolymer backbone or basic chain. The terpolymer may be added with mixing directly to the heated crude or in hydrocarbon solution such as a solution of the terpolymer in a middle distillate or kerosene. In another aspect, this invention relates to a process for the pipeline transportation of the crude oil compositions previously described.
