| 摘 要： | 以甲苯2,4-二异氰酸酯(TDI)、聚乙二醇(PEG800和PE G1000)、马来酸酐(MA)和三羟甲基丙烷(TMP)为主要原料,合成了2种水溶性聚氨酯表面活性剂(B1PEG800)和(B2PEG1000),用 FT-IR以及1HNMR对产物的分子结构进行了表征,并探讨了其最佳合成条件,同时对其CMC(临界胶束浓度)值、浊点和表面张力等性能进行了测定.结果表明,反应物在65 ℃反应4 h,并且在反应过程中添加35 mL丙酮/TDI/mol作为溶剂时产物的状态最好.用最大气泡压力法测得25 ℃B1 PEG800的临界胶束浓度为0.05 mol/L,此时的表面张力为33 mN/m;B2PEG1000的临界胶束浓度为0.037 5 mol/L,此时的表面张力为38.85 mN/m;溶液表现为牛顿型流体.

| Abstract: | Two waterborne surfactants(B1 PEG800 and B2 PEG1000) based on polyurethanes were synthesized by using 2,4-toluene dissocyanate(TDI),polyethylene glycol(PEG800 and PEG1000),maleic anhydride(MA) and trimethylolpropane(TMP) as feedstock,and were characterized by FT-IR and 1HNMR.The influential factors,such as the reaction temperature,reaction time and the amount of acetone were discussed.Some of their characters,such as the CMC,clouding point and the surface tension were also studied.The results show that the ... |
