Abstract: Styrylaryloxy ether sulfonates of the formula in which either R1 denotes styryl and simultaneously R2 and R3 are identical or different and denote hydrogen or styryl, or R1 and R2 are nonidentical and each denote methyl or styryl and simultaneously R3 denotes hydrogen or styryl, x denotes a number from 2 to 20, and M denotes an ammonium or alkali metal cation. These compounds are suitable as surfactant auxiliaries in oil recovery.
