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.
