In this paper, the synergic effect between 1, 4 - bis (3 - (dodecyloxylacyl) pyridinium) tutane) bromide (designated as NAE12 -4 -12) and sodium dodecyl benzene sulfate (SDBS), polyacrylamide (PAM) polyaerylic acid (PAA) have been studied. The results show that there is good synergic effect between NAE12 -4 - 12 and SDBS at NAE12 -4 - 12 :SDBS = 3:7. The cmc of the mixture of NAE12 -4 - 12 and SDBS is 0. 0031 mmol/L, which are two orders lower than that of NAE12 -4 - 12 solution free of SDBS. The value of-ycme reduces to 27.8 mN/m, which decreased by 44 mN/m compared with that of pure water. The critical aggregation concentrations of NAE12 -4 - 12 with PAM or PAA are higher than cme of NAE12 -4 - 12, and the γcat of mixture system is much lower than that of 0.01% PAM or PAA, suggesting that there is stronger interaction between NAE12 - 4- 12 and PAM/PPA.
