PU emulsion adhesive was synthesized with polyether diol and IPDI as primary materials and dimethylol propionic acid (DMPA) as hydrophilic monomer. The composition, the process of preparation and the properties of theadhesive were studied. By means of rotational viscosimeter , Autosizer, tensile tester and DSC, the emulsion or filmwas characterized and the effects of the percentage of hydrophilic monomer, the type of soft segment and different material-adding order on the performance of the emulsion and fi...
