Epoxy-enhanced nonionic waterborne polyurethane (EPU) was synthesized from epoxy resin (E51) and ethoxylated polymeric diol (D3403), and blended with polyacrylate (PA) to obtain the EPU/PA emulsion. The properties of EPU/PA were investigated. The results show that with increasing the EPU content of EPU/PA, the average particle size decreases and particle size distribution narrows. FT-IR tests indicate that epoxy groups between chains improve the compatibility of polymers. Atomic force microscopy (AFM) analysis shows that there is no significant phase separation. The single glass transition temperature（Tg）of EPU/PA, referring to the fitting curve of Davies equation, indicates that the compatibility of blends is good. The elongation at break and breaking strength of films increase from 135% to 337% and 11.5 MPa to 34.4 MPa,respectively, as increasing the EPU content of EPU/PA. The thermal stability of EPU/PA is better than that of EPU.
