Abstract
An anti-static fuel additive composition and method for using the composition to reduce or prevent buildup of electrostatic charge is described. The anti-static fuel additive composition comprises a polysulfone and a copolymer derived from reaction of an alkanolamine and a hydrocarbyl-substituted 4-membered to 7-memebered ring anhydride; for example, a hydrocarbyl-substituted succinic anhydride, a hydrocarbyl-substituted maleic anhydride, a hydrocarbyl-substituted phthalic anhydride, or a combination thereof.
