Four amphiphilic copolymers of 3-chloro-2-hydroxy-1-propanesulfonate sodium(NaCHPS) and 1-chloro-3-butoxy-2-propanol(CBP) were prepared via base-catalyzed polycondensation.The copolymers were characterized by means of FT-IR,1H and 13C NMR analysis.Vapor Pressure Osmometry(VPO) indicated the total number average molecular weights were in the range of 900~1600.The dynamic surface tension(DST) of sulfonated polyether aqueous solution with different mass concentrations and structures was measured via the plate method.The results show that when the mass concentration increases from 56.4 mg/L to 3 611 mg/L, the value of R1/2 increases from 11.04 mN/(m·min) to 7 662.5 mN/(m·min).Dynamic surface activity of sulfonated polyether increases with increasing sulfonated polyether concentration and 1-chloro-3-butoxy-2-propanol(CBP) unit.
