Wormlike micelles(WLMs)were formed in aqueous solutions of cationic trimer surfactant di(2-hydroxyl-dimethylene ether)-α

ω

γ-triple(dimethylcetylammonium chlorine)

referred to as 16-4(OH)-16-4(OH)-16 by addition of sodium salicylate(NaSal)and sodium chloride(NaCl).The rheological properties of the micellar solution before and after polymerization were discussed by solubilizing styrene(St)into the cores of WLMs.The temperature(T)and shear resistance of systems of 16-4(OH)-16-4(OH)-16/NaSal/NaCl and cetyl trimethyl ammonium bromide(CTAB)/NaSal were compared with the viscosimetry method

and the properties of 16-4(OH)-16-4(OH)-16/NaSal/NaCl solutions before and after polymerization were characterized with the rheology method.The results showed that the optimum solubilization quantity of St for the CTAB/NaSal system was 0.05 g

and at 100℃ or after shearing 90 min

the ηa of its polymerization system was 66.9 mPa·s and 15.5 mPa·s

respectively.For the 16-4(OH)-16-4(OH)-16/NaSal/NaCl system

the best solubilization quantity of St was 0.10 g;the ηa of its polymerization system was 99.1 mPa·s after shearing 90 min incessantly at 100℃;the plateau modulus(G0)of the polymerization system was higher than that of the solutions without St.Based on the above discussion

the "lock-in" of the microstructure of wormlike micelles formed by 16-4(OH)-16-4(OH)-16 with NaSal and NaCl can be realized by polymerization of St in the hydrophobic core of the micelles.
