A novel sulfonated polyurethane chain extender sodium trimethylol propane mono?propylene ether sulfonate (TMPMS) was prepared by the reaction of trimethylolpropane mono allyl ether (TMPME) and NaHSO3. The sulfonated polyurethane urea emulsion was prepared by adding ethylene urea ( EU) . The results showed that the emulsion stability was excellently, the critical solid content of emulsion by TMPMS and EU could reach 58?7%, which was higher than by carboxylic acid chain extender. The thermal resistance and mechanical properties of this film were higher than carboxylic acid polyurethane urea.
