摘要：

由甲苯二异氰酸酯、丙烯醇和不同分子量的聚乙烯醇合成了3种可聚合非离子表面活性剂（Ⅱ-PEG400、Ⅱ-PEG1000和Ⅱ-PEG2000），用FT-IR对分子结构进行了表征。 结果表明，随聚乙烯醇分子量的增加，非离子表面活性剂的电导率显著增加、表面张力由36.28 mN/m降低至31.30 mN/m、浊点由39.6 ℃增加至58.9 ℃，对丙烯酸丁酯(BA)、甲基丙烯酸甲酯(MMA)和甲基丙烯酸丁酯(BMA)的乳化能力均优于常用乳化剂OP-10，以AIBN作引发剂在70 ℃下既能均聚又可与丙烯酸酯进行共聚反应。

关键词: 可聚合非离子表面活性剂, 电导率；表面张力；乳化能力

Abstract:

Three polymerizable nonionic surfactants(Ⅱ-PEG400, Ⅱ-PEG1000, Ⅱ-PEG2000) were synthesized from 2,4-toluene dissocyanate(TDI), allyl alcohol and polyethylene glycol, and characterized by FT-IR. Results indicate that as the molecular mass of polyethylene glycol increases, the conductance is increased obviously, and the surface tension is decreased from 36.28 mN/m to 31.30 mN/m, while the cloud point is increased from 39.6  ℃ to 58.9 ℃. Their emulsifying abilities to BA, MMA and BMA are superior to that of OP-10, and the surfactants is homopolymerize or copolymerize with acrylate at 70 ℃ under the initiation of AIBN.

Key words: polymerizable nonionic surfactant, conductance；surface tension； emulsifying ability
