摘　　要：采用甲苯二异氰酸酯 (TDI) ,聚乙二醇 10 0 0 (PEG -10 0 0 ) ,丙烯酸为原料 ,通过分子设计合成了带有双键的非离子型可聚合乳化剂。并对其CMC值、流变行为及乳化力进行了表征。结果显示 :此乳化剂的CMC值在 6.0 %左右、浊点为 (54± 1)℃、HLB值为 16.1可以取代OP -10的乳化能力 ;该乳化剂可以与丙烯酸酯类单体进行乳液共聚 。A kind of nonionic polymerizable emulsifer was synthesized from 2,4-toluene diisocynate,PEG1000 and acrylate. The micelle solution behavior of polymerizable emulsifer, the critical micelle concentrations of it and the ability of emulsification were studied. The result shows: this polymerizable emulsifer's CMC is 6.0%; the chaotic point is (54±1)℃; the HLB is 16.1 and emulsifying power is equal to the emulsifying power of OP-10. The polymerizable emulsifer was used to co-polymerization with the kinds of acrylate, and the performance of this emulsion is more excellent than the polyacrylate emulsion.
