Abstract:

Four kinds of waterborne macromolecular sulfonate polyurethane surfactants（PUS） were synthesized via the acetone method with prepolymerization and chain extension,with toluene diiosocynate（TDI）,polyether glycol（PEG1000,PEG2000,PEG6000,PE6200） and self-prepared sulfonate diamine chain extender as raw materials.Then,the structures of the products were characterized by means of FT-IR,and the surface tension,critical micelle concentration（CMC）,emulsifying property and foaming property were investigated.The results show that the product with PEG as the substrate is of a CMC of about 20g/L,and the corresponding surface tension reaches 41.6mN/m,while that with PE6200 as the substrate is of a CMC of less than 1g/L and a surface tension of 32mN/m.

Key words: polyurethane, sulfonate, surfactant, critical micelle concentration, emulsifying property, foaming property
