A novel polymerizable borate ester surfactant(BE)was prepared by N-hydroxymethyl acrylamide,triethyl(borate) and N,N-dihydroxyethyl dodecylamine,and characterized and identified by IR,~1HNMR.The resistance to(hydrolysis),surface activity,homo-polymerization and co-polymerization(with acrylamide)properties of BE were(studied).The results showed that the BE has good resistance to hydrolysis,high surface activity with cmc(0.066 mmol/L) and γ_(cmc) 29.2 mN/m at 25 ℃,pH=7.Also,the BE has good homo-polymerization and co-polymerization properties,and the intrinsic viscosity of the two polymers achieve 24 mL/g and higher than 80 mL/g respectively.The γ_(cmc) are within(31.0 mN/m～)32.4 mN/m,which is similar with surface activity of conventional surfactants with low molecular weight.
