    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.
