| Abstract: | The existence of recrosslinking reaction during film forming process of reactive onepack polyurethane water dispersion was confirmed by IR.The film properties of dynamics and extraction rate in water,DMF and toluene were also determined.Results show that the film characteristics of tensile strength,elongation at break and solvent resistance improve obviously due to recrosslinking reaction. |

| Keywords: | polyurethane water dispersion recrosslinking reaction tensile strength elongation at break |
