Abstract

The polymeric surfactant with quaternary ammonium salt PQ was synthesized by cationic ringopen polymerization using boron trifluoride diethyletherate as cationic catalyst The chemical structure and aggregation behavior of PQ were studied by 1H NMR surface tension static light scattering dynamic laser light scattering electrical conductivity and fluorescence measurement The results show the surface tension γcmc and critical micelle concentration cmc of PQ decrease with increasing of sodium chloride concentration The cmc and γcmc values of PQ measured by electrical conductivity and fluorescence measurements mainly identify with that obtained by surface tension measurements The thermodynamic parameters Delta G m0 Delta H m0 Delta S m0 from electrical conductivity indicated that the micellization of PQ was mainly the process of entropydriven In addition the results from the viscosity stability between hydrolyzed polyacrylamide HPAM and PQ showed that the viscosities of mixed system for HPAM and PQ are higher than the viscosity of HPAM
