A new hydrophilic sulfonate monomer, 2,2-bis(hydroxymethyl) butyric propyl-3'-sodium sulfonate (DMBPS-Na), was synthesized by sulfo-alkylation reaction between 2,2-bis(hydroxymethyl) butyric acid sodium salt and 1,3-propane sultone. The structure of DMBPS-Na was further confirmed by FT-IR,1H-NMR, 13C-NMR, EIS-MS and elemental analysis. The melting point of the prepared DMBPS-Na is 85~90℃. It is soluble in water, ethanol, and dimethylacetamide (DMAC). It is slightly soluble in acetone or ethyl acetate. By using DMBPS-Na as hydrophilic monomer and PTMG-2000, IPDI and EDA as raw materials, the sulfonic type polyurethane dispersions (PUDs) with solid content above 50% were successfully synthesized through acetone process. The results from a performance test show that the average particle size of PUDs is 122.3 nm, the Zeta potential is?66.39 mV, the viscosity is 475 mPa?s and the PUDs is stable when the content of DMBPS-Na is 8 mmol?(100 g)?1 . The PUD colloidal particles have a spherical shape with bivariate distribution. The tensile stress of PUD films exceeds 10 MPa and the tensile strain at breaking point is about 1160%. The initial decomposition temperature of PUD films is about 270℃ and the fire decomposition is completed at 490℃.
