Abstract
It has been discovered that less expensive, and in some cases synergistically effective anti-static additive blends may be added to hydrocarbon fuels to improve the conductivity thereof. The blend includes an anti-static amount of at least one hydrocarbon soluble copolymer of an alkylvinyl monomer and a cationic vinyl monomer and an anti-static amount of at least one hydrocarbon soluble polysulfone copolymer of at least one olefin and sulfur dioxide. Optional ingredients include polymeric polyamines and aryl sulfonic acids.
