The microphase separation structure of carboxylic polyurethaneurea emulsions was studied by DSC,SEM and AXD,The results showed that the introduction of ionic groups into polyuretha neurea improved the microphase separation,and the soft segment segregation increased with the increase in the fraction of ionic groups.
