【摘要】 用浓硫酸与缩水甘油苯基醚-缩水甘油正丁基醚共聚物进行磺化反应合成了4种不同组成的缩水甘油苯基醚-缩水甘油正丁基醚共聚物磺酸钠,通过控制聚醚预聚体组成及其侧链上芳基的磺化度可控制磺酸聚醚的组成。用板法测定了磺酸聚醚水溶液表面张力随时间的变化,发现磺酸聚醚具有显著的表面张力时间效应,且随分子中缩水甘油正丁基醚(BGE)含量的增加,动态表面活性增强。用表面张力法测定了磺酸聚醚水溶液的cm c为1 400~780 mg/L,最低表面张力γm in为47.77~32.05 mN/m,且cm c和γm in均随分子中BGE含量的增加而减小。用透射电镜观察了胶束形态,受溶液浓度、物质结构等因素的影响,胶束形态各异、大小不均。更多还原

【Abstract】 Four sodium poly(phenyl glycidyl ether)-co-poly(butyl glycidyl ether) sulfonates(SPPBGE) were synthesized via the sulfonation of the polyether with sulfuric acid.The molecular structure of SPPBGE can be controlled by adjusting the constituent of polyether and sulfonation degree of its pendant phenyl.Dynamic(surface) tensions of SPPBGE water solutions were measured via the plate method,the result shows that the(dynamic) surface activity increases with increasing butyl glycidyl ether content in SPPBGE.Critic micell(concentrations) and minimum surface tensions were determined via surface tension measurement,they are in the ranges of 1 400~780 mg/L and 47.77~32.05 mN/m respectively,and they decrease with increasing butyl glycidyl ether content in SPPBGE.Micell morphologies of SPPBGE in water were observed with TEM,they change with the concentration and molecular structure.更多还原
