Abstract：Toluene disocyanate （TDI），dihydroxymethylpropionicacid（DMPA）and polyester polyol were used as raw materials，and then self-emulsified in water after distribution prepolymerization，and the performance of adhesives made from them was studied. The results showed that when the DMPA content was 3%～8% ，the adhesive performance was stable，and its viscosity would increase withthe gradual increaseofDMPAcontent.There were certain diferences inreaction timeand temperature indiferent reactionstages.The additionof deionized water，salt formationand emulsificationat the same time could achieve good emulsion performance.Ading water dissolved with triethylamine to the prepolymer could effectively avoid the aggregation of particles after dispersion and achieve good emulsion performance.
