摘　　要：反应型乳化剂(RE)既具有优良的乳化功能,又可与反应体系内的单体共聚。以聚乙二醇、2,4-甲苯二异氰酸酯为原料,加入一定量的丙烯酰胺,合成了RE,并用FT-IR、特性黏度测试等手段,表征了这种反应型乳化剂的化学结构,并对其浊点、乳化性能进行了研究。The reactive emulsifier （RE） not only has excellent emulsifying function but also can co-polymerize with the monomers in reaction systems. In this experiment, the RE was synthesized by using polyethylene glycol and 2,4-toluene diisocyanate as raw materials and adding a certain amount of acrylamide. The chemical structure of this RE was characterized by using the means such as FT-IR, characteristic viscosity, and so on. And its cloud point and emulsifying performance were studied.
