摘　　要：以聚己二酸丁二醇酯二醇、异佛尔酮二异氰酸酯、乙二胺为原料,由自制的乙二胺基乙磺酸钠为亲水性扩链剂,采用预聚体法合成磺酸型水性聚氨酯分散液。研究发现,磺酸型水性聚氨酯分散液固含量高(43.66%),稳定性大于6个月,且性能优于羧酸型水性聚氨酯分散液。A waterborne polyurethane dispersions （PUD） containing SO3 Na group was synthesized by prepolymerization process with PBA3000, IPDI, EDA as raw materials and home -made aliphatic diamine sulphonate as hydrophilic chain extender. The results indicated that the solid content of the dispersions （43.66%） was higher than that of waterborne polyurethane containing COO- group, their stability was over 6 months, and their properties were superior to these of waterborne polyurethane containing COO- group.
