可聚合非离子型表面活性剂的合成及其性能
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36.28mN/m降低至31.30mN/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。

Synthesis and Characterization of Polymerizable Nonionic Surfactants
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.
