    摘要: Middle distillate oils are improved with respect to flow and pour point by incorporating therein halogenated polymers comprised of ethylene and free radical polymerizable monomers containing polar groups. The halogenated ethylene-polar monomer copolymers are found to be more effective flow improvers and pour depressants than non-halogenated ethylene-polar monomer copolymers. Preferred polymeric additives include the ethylene-isobutyl acrylate copolymers and the ethylene-vinyl acetate copolymers containing from about 5 to about 25 wt.% chlorine.

    摘要: Sulfone copolymeric oil additives having utility as a lubricating oil pour point depressant, viscosity index improver, dispersant, load carrying agent, rust inhibitor and/or antioxidant, or as a cold flow improver for heavy distillates and residual fuels, comprise the hydrocarbon soluble copolymers of an ethylenically unsaturated polar monomer and sulfur dioxide. This sulfone copolymer may contain one or more additional monomers including: C.sub.2 to C.sub.50, preferably at least C.sub.6, substantially linear alpha olefins; C.sub.2 to C.sub.12, preferably C.sub.2 to C.sub.9, cyclic olefins; and, C.sub.4 to C.sub.6 conjugated diolefins.
